+.SH DESCRIPTION
+The
+.ZN XmbTextExtents ,
+.ZN XwcTextExtents
+and
+.ZN Xutf8TextExtents
+functions set the components of the specified overall_ink_return and
+overall_logical_return
+arguments to the overall bounding box of the string's image
+and a logical bounding box for spacing purposes, respectively.
+They return the value returned by
+.ZN XmbTextEscapement ,
+.ZN XwcTextEscapement
+or
+.ZN Xutf8TextEscapement .
+These metrics are relative to the drawing origin of the string,
+using the fonts loaded for the specified font set.
+.LP
+If the overall_ink_return argument is non-NULL,
+it is set to the bounding box of the string's character ink.
+The overall_ink_return for a nondescending, horizontally drawn
+Latin character is conventionally entirely above the baseline;
+that is, overall_ink_return.height <= \-overall_ink_return.y.
+The overall_ink_return for a nonkerned character
+is entirely at, and to the right of, the origin;
+that is, overall_ink_return.x >= 0.
+A character consisting of a single pixel at the origin would set
+overall_ink_return fields y = 0, x = 0, width = 1, and height = 1.
+.LP
+If the overall_logical_return argument is non-NULL,
+it is set to the bounding box that provides minimum spacing
+to other graphical features for the string.
+Other graphical features, for example, a border surrounding the text,
+should not intersect this rectangle.
+.LP
+When the
+.ZN XFontSet
+has missing charsets,
+metrics for each unavailable character are taken
+from the default string returned by
+.ZN XCreateFontSet
+so that the metrics represent the text as it will actually be drawn.
+The behavior for an invalid codepoint is undefined.
+.LP
+The function
+.ZN Xutf8TextExtents
+is an extension introduced by The XFree86 Project, Inc. in their 4.0.2
+release. Its presence is
+indicated by the macro
+.ZN X_HAVE_UTF8_STRING .
