This paper describes -the Input Method Protocol developed for X11R6 to resolve the above problems -and to address the requirements of existing and future input methods. -.LP -The Input Method Protocol is independent from the transport layer used in -communication between the IM library and the IM Server. -Thus, the input method protocol can be built on any inter-process -communication mechanism, such as TCP/IP or the X protocol. -.LP -In addition, the protocol provides for future extensions such as differing -input model types. -.LP -.NH 2 -Background -.XS -\*(SN Background -.XE -.LP -Text input is much more simple for some languages than -others. English, for instance, uses an alphabet of a manageable size, -and input consists of pressing the corresponding key on a keyboard, -perhaps in combination with a shift key for capital letters or special -characters. -.LP -Some languages have larger alphabets, or modifiers such as accents, -which require the addition of special key combinations in order to enter -text. These input methods may require ``dead-keys'' or ``compose-keys'' -which, when followed by different combinations of key strokes, -generate different characters. -.LP -Text input for ideographic languages is much less simple. In these -languages, characters represent actual objects rather than phonetic -sounds used in pronouncing a word, and the number of characters -in these languages may continue to grow. In Japanese, for instance, most -text input methods involve entering characters in a phonetic alphabet, -after which the input method searches a dictionary for possible -ideographic equivalents (of which there may be many). The input method then -presents the candidate characters for the user to choose from. -.LP -In Japanese, either Kana (phonetic symbols) or Roman letters are -typed and then a region is selected for conversion to Kanji. Several -Kanji characters may have the same phonetic representation. If that -is the case with the string entered, a menu of characters is presented -and the user must choose the appropriate one. If no choice is necessary -or a preference has been established, the input method does the -substitution directly. -.LP -These complicated input methods must present state information (Status Area), -text entry and edit space (Preedit Area), and menu/choice presentations -(Auxiliary Area). Much of the protocol between the IM library and the IM -Server involves managing these IM areas. -Because of the size and complexity of these input methods, and because -of how widely they vary from one language or locale to another, they are -usually implemented as separate processes which can serve many client -processes on the same computer or network. -.LP -.NH 2 -Input Method Styles -.XS -\*(SN Input Method Styles -.XE -.LP -X11 internationalization support includes the following four types of -input method: -.RS -.IP "- on-the-spot:" 20 -The client application is directed by the IM Server to display all -pre-edit data at the site of text insertion. The client registers -callbacks invoked by the input method during pre-editing. -.IP "- off-the-spot:" 20 -The client application provides display windows for the pre-edit data -to the input method which displays into them directly. -.IP "- over-the-spot:" 20 -The input method displays pre-edit data in a window which it brings up -directly over the text insertion position. -.IP "- root-window:" 20 -The input method displays all pre-edit data in a separate area of the -screen in a window specific to the input method. -.RE -.LP -Client applications must choose from the available input methods -supported by the IM Server and provide the display areas and callbacks -required by the input method. -.LP -.NH 1 -Architecture -.XS -\*(SN Architecture -.XE -.NH 2 -Implementation Model -.XS -\*(SN Implementation Model -.XE -.LP -Within the X Window System environment, the following two typical -architectural models can be used as an input method's implementation -model. -.RS -.IP "- Client/Server model:" 20 -A separate process, the IM Server, processes input and handles preediting, -converting, and committing. The IM library within the application, acting -as client to the IM Server, simply receives the committed string from the -IM Server. -.IP "- Library model:" 20 -All input is handled by the IM library within the application. The -event process is closed within the IM library and a separate IM Server -process may not be required. -.RE -.LP -Most languages which need complex preediting, such as Asian languages, -are implemented using the Client/Server IM model. Other languages -which need only dead key or compose key processing, such as European -languages, are implemented using the Library model. -.LP -In this paper, we discuss mainly the Client/Server IM model and the -protocol used in communication between the IM library (client) and the IM -Server. -.LP -.NH 2 -Structure of IM -.XS -\*(SN Structure of IM -.XE -.LP -When the client connects or disconnects to the IM Server, an open or close -operation occurs between the client and the IM Server. -.LP -The IM can be specified at the time of XOpenIM() by setting the locale -of the client and a locale modifier. Since the IM remembers -the locale at the time of creation XOpenIM() can be called -multiple times (with the -setting for the locale and the locale modifier changed) to support -multiple languages. -.LP -In addition, the supported IM type can be obtained using XGetIMValues(). -.LP -The client usually holds multiple input (text) fields. Xlib provides a -value type called the ``Input Context'' (IC) to manage each individual -input field. An IC can be created by specifying XIM using XCreateIC(), -and it can be destroyed using XDestroyIC(). -.LP -The IC can specify the type of IM which is supported by XIM for each -input field, so each input field can handle a different type of IM. -.LP -Most importantly information such as the committed string sent from -the IM Server to the client, is exchanged based on each IC. -.LP -Since each IC corresponds to an input field, the focused input field -should be announced to the IM Server using XSetICFocus(). (XUnsetICFocus() -can also be used to change the focus.) -.LP -.NH 2 -Event Handling Model -.XS -\*(SN Event Handling Model -.XE -.LP -Existing input methods support either the FrontEnd method, the BackEnd method, -or both. This protocol specifically supports the BackEnd method as -the default method, but also supports the FrontEnd method as an optional -IM Server extension. -.LP -The difference between the FrontEnd and BackEnd methods is in how -events are delivered to the IM Server. (Fig. 1) -.LP -.NH 3 -BackEnd Method -.XS -\*(SN BackEnd Method -.XE -.LP -In the BackEnd method, client window input events are always delivered -to the IM library, which then passes them to the IM Server. Events are -handled serially in the order delivered, and therefore there is no -synchronization problem between the IM library and the IM Server. -.LP -Using this method, the IM library forwards all KeyPress and KeyRelease -events to the IM Server (as required by the Event Flow Control model -described in section 2.4. ``Event Flow Control''), and synchronizes -with the IM Server (as described in section 4.16. ``Filtering Events''). -.LP -.NH 3 -FrontEnd Method -.XS -\*(SN FrontEnd Method -.XE -.LP -In the FrontEnd method, client window input events are delivered by the -X server directly to both the IM Server and the IM library. Therefore this -method provides much better interactive performance while preediting -(particularly in cases such as when the IM Server is running locally on -the user's workstation and the client application is running on another -workstation over a relatively slow network). -.LP -However, the FrontEnd model may have synchronization problems between -the key events handled in the IM Server and other events handled in the -client, and these problems could possibly cause the loss or duplication -of key events. For this reason, the BackEnd method is the core method -supported, and the FrontEnd method is made available as an extension for -performance purposes.

On the other hand, key events necessary for composing Chinese -characters must be sent to the IM Server. -.LP -Thus, by adopting the Dynamic Event Flow, the number of requests among the -X Server, the client, and the IM Server is significantly reduced, and the -number of context switches is also reduced, resulting in improved performance. -The IM Server can send -.PN XIM_REGISTER_TRIGGERKEYS -message in order to switch the event flow in the Dynamic Event Flow. -.LP -The protocol for this process is described in section 4.5. ``Event Flow -Control''. -.LP -.NH 1 -Default Preconnection Convention -.XS -\*(SN Default Preconnection Convention -.XE -.LP -IM Servers are strongly encouraged to register their symbolic -names as the ATOM names into the IM Server directory property, -.PN XIM_SERVERS, -on the root window of the screen_number 0. -This property can contain a list of ATOMs, and the each ATOM represents -each possible IM Server. -IM Server names are restricted to POSIX Portable Filename Character Set. -To discover if the IM Server is active, see if there is an owner for -the selection with that atom name.

Also, the IM Server needs to synchronously -process the correspondent reply from the IM library and the following -.PN XIM_FORWARD_EVENT -message sent from the IM library when any of the event causes the IM Server -to send -.PN XIM_FORWARD_EVENT -or -.PN XIM_COMMIT -message to the IM library, so that the input service is consistent. If the -IM library gets the control back from the application after receiving the -synchronous request, the IM library replies for the synchronous request before -processing any of the events. In this time, the IM Server blocks -.PN XIM_FORWARD_EVENT -message which is sent by the IM library, and handles it after receiving the -reply. However, the IM Server handles the other protocols at any time. -.LP -In full-synchronous method, the IM library always sends -.PN XIM_FORWARD_EVENT -message to the IM Server as a synchronous request. Therefore, the reply to it -from the IM Server will be put between the -.PN XIM_FORWARD_EVENT -message and its -.PN XIM_SYNC_REPLY -message. -In case of sending -.PN XIM_FORWARD_EVENT -or -.PN XIM_COMMIT -message, the IM Server should set the synchronous flag off.

+The internationalization in the
+X Window System
+Version 11, Release 5 (X11R5) provides a common API which application
+developers can use to create portable internationalized programs and to
+adapt them to the requirements of different native languages, local customs,
+and character string encodings (this is called "localization").
+As one of its internationalization mechanisms X11R5 has defined a functional
+interface for internationalized text input, called XIM (X Input Method).
+</para>
+<para>
+<!-- .LP -->
+When a client-server model is used with an IM (Input Method) implementation,
+a protocol must be established between the client and the server.
+However, the protocol used to interface Input Method Servers (IM Servers)
+with the Input Method libraries (IM libraries) to which applications are
+linked was not addressed in X11R5.
+This led application developers to depend on vendor-specific input methods,
+decreased the user's choice of available input methods, and made it more
+difficult for developers to create portable applications. This paper describes
+the Input Method Protocol developed for X11R6 to resolve the above problems
+and to address the requirements of existing and future input methods.
+</para>
+<para>
+<!-- .LP -->
+The Input Method Protocol is independent from the transport layer used in
+communication between the IM library and the IM Server.
+Thus, the input method protocol can be built on any inter-process
+communication mechanism, such as TCP/IP or the X protocol.
+</para>
+<para>
+In addition, the protocol provides for future extensions such as differing
+input model types.

+Text input is much more simple for some languages than
+others. English, for instance, uses an alphabet of a manageable size,
+and input consists of pressing the corresponding key on a keyboard,
+perhaps in combination with a shift key for capital letters or special
+characters.
+</para>
+<para>
+<!-- .LP -->
+Some languages have larger alphabets, or modifiers such as accents,
+which require the addition of special key combinations in order to enter
+text. These input methods may require "dead-keys" or "compose-keys"
+which, when followed by different combinations of key strokes,
+generate different characters.
+</para>
+<para>
+<!-- .LP -->
+Text input for ideographic languages is much less simple. In these
+languages, characters represent actual objects rather than phonetic
+sounds used in pronouncing a word, and the number of characters
+in these languages may continue to grow. In Japanese, for instance, most
+text input methods involve entering characters in a phonetic alphabet,
+after which the input method searches a dictionary for possible
+ideographic equivalents (of which there may be many). The input method then
+presents the candidate characters for the user to choose from.
+</para>
+<para>
+<!-- .LP -->
+In Japanese, either Kana (phonetic symbols) or Roman letters are
+typed and then a region is selected for conversion to Kanji. Several
+Kanji characters may have the same phonetic representation. If that
+is the case with the string entered, a menu of characters is presented
+and the user must choose the appropriate one. If no choice is necessary
+or a preference has been established, the input method does the
+substitution directly.
+</para>
+<para>
+<!-- .LP -->
+These complicated input methods must present state information (Status Area),
+text entry and edit space (Preedit Area), and menu/choice presentations
+(Auxiliary Area). Much of the protocol between the IM library and the IM
+Server involves managing these IM areas.
+Because of the size and complexity of these input methods, and because
+of how widely they vary from one language or locale to another, they are
+usually implemented as separate processes which can serve many client
+processes on the same computer or network.

+The IM can be specified at the time of XOpenIM() by setting the locale

+In addition, the supported IM type can be obtained using XGetIMValues().

+The client usually holds multiple input (text) fields. Xlib provides a

+and it can be destroyed using XDestroyIC().
+</para>

+The IC can specify the type of IM which is supported by XIM for each

+Existing input methods support either the FrontEnd method, the BackEnd method,

+In the BackEnd method, client window input events are always delivered

+In the FrontEnd method, client window input events are delivered by the
+X server directly to both the IM Server and the IM library. Therefore this
+method provides much better interactive performance while preediting
+(particularly in cases such as when the IM Server is running locally on
+the user's workstation and the client application is running on another
+workstation over a relatively slow network).
+</para>
+<para>
+<!-- .LP -->
+However, the FrontEnd model may have synchronization problems between
+the key events handled in the IM Server and other events handled in the
+client, and these problems could possibly cause the loss or duplication
+of key events. For this reason, the BackEnd method is the core method
+supported, and the FrontEnd method is made available as an extension for
+performance purposes. (Refer to

+<!-- .LP -->
+This protocol supports two event flow models for communication between the
+IM library and the IM Server (Static and Dynamic).
+</para>
+<para>
+<!-- .LP -->
+Static Event Flow requires that input events always be sent to the IM
+Server from the client.
+</para>
+<para>
+<!-- .LP -->
+Dynamic Event Flow, however, requires only that those input events which
+need to be processed (converted) be sent to the IM Server from the client.
+</para>
+<para>
+<!-- .LP -->
+For instance, in the case of inputing a combination of ASCII characters
+and Chinese characters, ASCII characters do not need to be processed in
+the IM Server, so their key events do not have to be sent to the IM
+Server. On the other hand, key events necessary for composing Chinese
+characters must be sent to the IM Server.
+</para>
+<para>
+<!-- .LP -->
+Thus, by adopting the Dynamic Event Flow, the number of requests among the
+X Server, the client, and the IM Server is significantly reduced, and the
+number of context switches is also reduced, resulting in improved performance.
+The IM Server can send
+<function>XIM_REGISTER_TRIGGERKEYS </function>
+message in order to switch the event flow in the Dynamic Event Flow.

+IM Servers are strongly encouraged to register their symbolic
+names as the ATOM names into the IM Server directory property,
+<function>XIM_SERVERS,</function>
+on the root window of the screen_number 0.
+This property can contain a list of ATOMs, and the each ATOM represents
+each possible IM Server.
+IM Server names are restricted to POSIX Portable Filename Character Set.
+To discover if the IM Server is active, see if there is an owner for
+the selection with that atom name. To learn the address of that IM Server,
+convert the selection target
+<function>TRANSPORT,</function>
+which will return a string form of the transport address(es).
+To learn the supported locales of that IM Server, convert the selection target
+<function>LOCALES,</function>
+which will return a set of names of the supported locales in the syntax
+X/Open defines.

+

+With BackEnd method, the protocol flow can be classified into two

+message. One can be called on-demand-synchronous method and another
+can be called as full-synchronous method.
+</para>
+
+<para>
+In on-demand-synchronous method, the IM library always receives
+<function>XIM_FORWARD_EVENT</function>
+or
+<function>XIM_COMMIT</function>
+message as a synchronous request. Also, the IM Server needs to synchronously
+process the correspondent reply from the IM library and the following
+<function>XIM_FORWARD_EVENT</function>
+message sent from the IM library when any of the event causes the IM Server
+to send
+<function>XIM_FORWARD_EVENT</function>
+or
+<function>XIM_COMMIT</function>
+message to the IM library, so that the input service is consistent. If the
+IM library gets the control back from the application after receiving the
+synchronous request, the IM library replies for the synchronous request before
+processing any of the events. In this time, the IM Server blocks
+<function>XIM_FORWARD_EVENT</function>
+message which is sent by the IM library, and handles it after receiving the
+reply. However, the IM Server handles the other protocols at any time.
+</para>
+
+<para>
+In full-synchronous method, the IM library always sends
+<function>XIM_FORWARD_EVENT</function>
+message to the IM Server as a synchronous request. Therefore, the reply to it
+from the IM Server will be put between the
+<function>XIM_FORWARD_EVENT</function> message and its
+<function>XIM_SYNC_REPLY</function> message. In case of sending
+<function>XIM_FORWARD_EVENT</function> or
+<function>XIM_COMMIT</function>

+<para>
+(1) FrontEnd Method
+</para>
+
+<para>
+FrontEnd method is recognized as a performance acceleration by the
+trade off of the variety of the reliability.
+</para>
+
+<para>
+In order to use the FrontEnd method, the IM library must query the IM
+Server to see if the FrontEnd extension is available. The query is
+made by using the
+<function>XIM_QUERY_EXTENSION</function>
+message. The IM Server may send
+<function>XIM_EXT_SET_EVENT_MASK</function>
+message with intercept-event-mask, forward-event-mask, and
+synchronous-event-mask values set after replying
+<function>XIM_QUERY_EXTENSION_REPLY</function>
+message.
+</para>
+
+<para>
+FrontEnd method can be implemented in a couple of ways depending on
+how the IM Server utilize
+<function>XIM_EXT_SET_EVENT_MASK</function>
+message.
+</para>
+
+<para>
+One approach is to update both of the input mask and the filter-event-mask
+depending on the preeidting state. The sample protocol sequence using the
+static event flow is as follows:
+</para>
+
+<mediaobject id="staticflow">
+ <imageobject>
+ <imagedata scale="75" format="SVG" fileref="staticflow.svg"/>
+ </imageobject>
+ <caption>The flow of events</caption>
+</mediaobject>
+
+<para>
+To pursuit a maximum performance regardless of the preediting mode,
+the IM Server may use the dynamic event flow with the following
+sample protocol sequence.
+</para>
+
+<mediaobject id="dynamicflow">
+ <imageobject>
+ <imagedata scale="75" format="SVG" fileref="dynamicflow.svg"/>
+ </imageobject>
+ <caption>The flow of events</caption>
+</mediaobject>
+
+<para>
+This method can reduce the XIM protocol traffic dramatically
+by updating intercept-event-mask and select-event-mask accordingly.
+The tradeoff of this performance improvement is that the key
+events may be lost or disordered in some particular situation, such as
+when the user types the keyboard in following sequence really fast:
+</para>
+
+<para>
+<preediting on key>"some strings"<preediting off
+key>"another string"
+</para>
+
+<para>
+Since this method requires the input mask updates to the both the IM Server
+and Xlib when turning on and off the preediting, and there is a time lag
+till the requests take effect when two client issues the input mask updates
+simultaneously.
+</para>
+
+<para>
+Another approach of the FrontEnd method is to update the filter-event-mask
+depending on the preediting state and not to update the input mask.
+The IM Server must register both of the preediting on key list and off key
+list by
+<function>XIM_REGISTER_TRIGGERKEYS</function>
+message.
+In this method, Both the IM Server and the IM client select the same
+events on the same client's window, so that the events are delivered
+to both of the IM Server and the client. The preediting on and off
+states are expressed by whether the key events are filtered or not.
+The sample protocol sequence are as follows:
+</para>
+
+<para>
+<<Using static event flow>>
+</para>
+
+<mediaobject id="staticflowsampleseq">
+ <imageobject>
+ <imagedata scale="75" format="SVG" fileref="staticflowsampleseq.svg"/>
+ </imageobject>
+ <caption>The flow of events</caption>
+</mediaobject>
+
+<para>
+<<Using the dynamic event flow>>
+</para>
+
+<mediaobject id="dynamicflowsampleseq">
+ <imageobject>
+ <imagedata scale="75" format="SVG" fileref="dynamicflowsampleseq.svg"/>
+ </imageobject>
+ <caption>The flow of events</caption>
+</mediaobject>
+
+<para>
+This method does not have the problem of the time lag when going across
+the preediting on and off mode, however, the amount of the performance
+acceleration is not as good as the method described above.
+</para>
+
+<para>
+In general, the FrontEnd method requires some synchronization to some
+of the X protocols, such as the ChangeWindowAttribute protocol for the
+event mask change or the GrabKey protocol, since it relies on the X's
+principal event dispatching mechanism. Any X protocol bindings do not
+consider the synchronization might cause some mis-synchronization
+between the IM clients and the IM Server.
+</para>
+
+<para>
+(2) Transport Layer
+</para>
+
+<para>
+The Xlib XIM implementation is layered into three functions, a protocol
+layer, an interface layer and a transport layer. The purpose of this
+layering is to make the protocol independent of transport implementation.
+Each function of these layers are:
+</para>
+
+<variablelist>
+ <varlistentry>
+ <term>The protocol layer</term>
+ <listitem>
+ <para>
+implements overall function of XIM and calls the interface layer
+functions when it needs to communicate to IM Server.
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>The interface layer</term>
+ <listitem>
+ <para>
+separates the implementation of the transport layer from the protocol
+layer, in other words, it provides implementation independent hook for
+the transport layer functions.
+ </para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>The transport layer</term>
+ <listitem>
+ <para>
+handles actual data communication with IM Server. It is done by a set
+of several functions named transporters.
+ </para>
+ </listitem>
+ </varlistentry>
+</variablelist>
+
+<para>
+The interface layer and the transport layer make various communication
+channels usable such as X Protocol, TCP/IP, DECnet or STREAM.
+The following is a sample implementation for the transporter using
+the X connection.
+Refer to "xtrans" for the transporter using Socket Transport. <!-- xref ?-->
+</para>
+
+<para>
+At the beginning of the X Transport connection for the XIM transport
+mechanism, two different windows must be created either in an Xlib XIM
+or in an IM Server, with which the Xlib and the IM Server exchange the
+XIM transports by using the ClientMessage events and Window Properties.
+In the following, the window created by the Xlib is referred as the
+"client communication window", and on the other hand, the window created
+by the IM Server is referred as the "IMS communication window".
+</para>
+
+<para>
+Connection
+</para>
+
+<para>
+In order to establish a connection, a communication window is created.
+A ClientMessage in the following event's format is sent to the owner
+window of XIM_SERVER selection, which the IM Server has created.
+</para>

+<para>
+Refer to "The Input Method Protocol" for the XIM_SERVER atom. <!-- xref -->

-Dependent X, LDX) consists of three objects; -locale (LC) , input method (IM) and output method (OM). -The LC provides a set of information that depends on user's language -environment. The IM manages text inputing, and the OM manages text -drawing. Both IM and OM highly depend on LC data. -.LP -In X11R5, there are two sample implementations, Ximp and Xsi, for -Xlib internationalization. But in both implementations, IM and OM -actually refer the private extension of LC. It breaks coexistence -of these two sample implementations. For example, if a user creates -a new OM for special purpose as a part of Ximp, it will not work with -Xsi. -.LP -As a solution of this problem, we propose to define the standard -APIs between these three objects, and define the structure that are -common to these objects. -.LP -.NH 1 -Objective -.XS \*(SN Objective -.XE -.LP -.IP \(bu -Explain the current X11R6 sample implementation -.IP \(bu -Document the common set of locale dependent interfaces -.IP \(bu -Provide more flexible pluggable layer -.LP -.NH 1 -Locale Object Binding Functions -.XS \*(SN Locale Object Binding Functions -.XE -.LP -This chapter describes functions related locale object binding for -implementing the pluggable layer. -.LP -A locale loader is an entry point for locale object, which -instantiates XLCd object and binds locale methods with specified -locale name.

+This document proposes to define the structures, methods and their
+signatures that are expected to be common to all locale dependent
+functions within the Xlib sample implementation. The following

+Generally speaking, the internationalized portion of Xlib (Locale
+Dependent X, LDX) consists of three objects;
+locale (LC) , input method (IM) and output method (OM).
+The LC provides a set of information that depends on user's language
+environment. The IM manages text inputing, and the OM manages text
+drawing. Both IM and OM highly depend on LC data.
+</para>
+
+<para>
+In X11R5, there are two sample implementations, Ximp and Xsi, for
+Xlib internationalization. But in both implementations, IM and OM
+actually refer the private extension of LC. It breaks coexistence
+of these two sample implementations. For example, if a user creates
+a new OM for special purpose as a part of Ximp, it will not work with
+Xsi.
+</para>
+
+<para>
+As a solution of this problem, we propose to define the standard
+APIs between these three objects, and define the structure that are
+common to these objects.

+A locale loader is an entry point for locale object, which
+instantiates XLCd object and binds locale methods with specified
+locale name. The behavior of loader is implementation dependent.

+It is provided as a plain ASCII text file, so a user can change its
+contents easily. It allows a user to customize the behavior of

+<para>
+The X Locale Database contains one or more category definitions.
+This section describes the format of each category definition.
+</para>
+
+<para>
+The category definition consists of one or more class definitions.
+Each class definition has a pair of class name and class value, or
+has several subclasses which are enclosed by the left brace ({) and
+the right brace (}).
+</para>
+
+<para>
+Comments can be placed by using the number sign character (#).
+Putting the number sign character on the top of the line indicates
+that the entire line is comment. Also, putting any whitespace character
+followed by the number sign character indicates that a part of the line
+(from the number sign to the end of the line) is comment.
+A line can be continued by placing backslash (\) character as the
+last character on the line; this continuation character will be
+discarded from the input. Comment lines cannot be continued on
+a subsequent line using an escaped new line character.
+</para>
+
+<para>
+X Locale Database only accepts XPCS, the X Portable Character Set.
+The reserved symbols are; the quotation mark("), the number sign (#),
+the semicolon(;), the backslash(\), the left brace({) and
