/*
* HISTORY
* $Log: from_SJIS.c,v $
* Revision 1.1.14.1 2001/12/07 15:37:41
* * Enable __UDC_to_sjis() to return 0 for conversion table lookup.
* * Merge codes from kernel/bsd.
*
* Revision 1.1.10.1 2000/01/13 20:25:32
* Remove the old conversion routine in favor of the enhanced
* __<codeset>_index() routine, and add algorithmic UDC conversion
* support. Also add a number of conversion routines to support
* special font charset to Unicode conversion.
*
* Revision 1.1.8.2 1998/03/26 18:55:46
* Prepend __ to global functions to prevent namespace pollution
* and add __<codeset>__index function for use by UCS-4 locale method.
* [1998/03/23 14:42:08 Long_Man]
*
* Revision 1.1.6.2 1996/11/22 17:02:14
* Improve execution speed & other minor bug fixes.
* [1996/11/12 17:18:45 Long_Man]
*
* Consolidate UCS iconv converter binaries & support UCS-2.
* [1996/10/28 21:10:56 Long_Man]
*
* Revision 1.1.2.3 1995/06/30 14:44:48
* Fix pointer and length settings for E2BIG errors
* [1995/06/30 13:31:15 Bill_Fountas]
*
* Revision 1.1.2.2 1995/06/07 16:12:16
* Initial iconv Unicode support check in
* [1995/06/02 14:58:14 Kelly_Mulheren]
