- * Notes:
- * 1.  16-bit widechar format is limited to 14 data bits.  Since the 2nd byte
- *     of SJIS multibyte chars are in the ranges of 0x40 - 7E and 0x80 - 0xFC,
- *     SJIS cannot map directly into 16 bit widechar format within the confines
- *     of a single codeset.  Therefore, for SJIS widechar conversion, SJIS Kanji
- *     is mapped into the JIS codeset.  (The algorithms used in jis_to_sjis()
- *     and sjis_to_jis() are from Ken Lunde (lunde@mv.us.adobe.com) and are in
- *     the public domain.)
- * 2.  Defining FORCE_INDIRECT_CONVERTER (see _XlcEucLoader())
- *     forces indirect (charset) conversions (e.g. wcstocs()<->cstombs()).
- * 3.  Using direct converters (e.g. mbstowcs()) decreases conversion
- *     times by 20-40% (depends on specific converter used).
