+ * 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
