00032 
00033     This function translates the specified ansi character to unicode and
00034     returns the unicode value.  The purpose for this routine is to allow
00035     for character by character ansi to unicode translation.  The
00036     translation is done with respect to the current system locale
00037     information.
00038 
00039 
00040 Arguments:
00041 
00042     SourceCharacter - Supplies a pointer to an ansi character pointer.
00043         Through two levels of indirection, this supplies an ansi
00044         character that is to be translated to unicode.  After
00045         translation, the ansi character pointer is modified to point to
00046         the next character to be converted.  This is done to allow for
00047         dbcs ansi characters.
00048 
00049 Return Value:
00050 
00051     Returns the unicode equivalent of the specified ansi character.
