| * HISTORY |
| * $Log: from_ksc5601.c,v $ |
| * Revision 1.1.10.1 2001/12/07 15:37:50 |
| * * Enable mapping of all unassigned codepoints to UDC. |
| * |
| * Revision 1.1.6.1 2000/01/13 20:25:42 |
| * 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 1.1.4.2 1998/03/26 18:56:18 |
| * Prepend __ to global functions to prevent namespace pollution |
| * and add __<codeset>__index function for use by UCS-4 locale method. |
| * [1998/03/23 14:42:31 Long_Man] |
| * |
| * Revision 1.1.2.2 1997/03/07 18:54:07 |
| * New multibyte to table index converter for KSC 5601-1992. |
