Linux Kernel 2.4.x NLS Patch, This Patch is used to correct problems of translation tables of CP932, CP936, CP949 and CP950.
There are 2 problems:
1. Translation Tables
In the "linux/fs/nls_cp936.c (ncl_cp932.c, nls_cp949.c and nls_cp950.c)", the translation tables were downloaded from
http://www.microsoft.com/typography/unicode/unicodecp.htm,
but the page was not found. The new Codepage is located at:
http://www.microsoft.com/globaldev/reference/cphome.mspx.
After examination the old one and new one, can find much more different,
e.g., 0x8179 in the CP936 should be corresponding with 0x4E82 in Unicode,
NOT 0xF91B. So, need rebuid the C program.
2. Area between 0x80 and 0xFF in the Unicode
The area between 0x80 and 0xFF in the Unicode, is not be corresponding with CP932, CP936, CP949 and CP950: part of this can have corresponding letters,
others not have. The old uni2char() function is not correct for dealing with this area, because it let 0x80-0xFF keep the same, but it's not true.
e.g., the Unicode letter 0x00A4 should be corresponding with 0xA1E8 of the Codepage 936, not keep itself.
