1./cvsroot/bf-blender/blender/config/win32-vc-config.py
I don't know how to link iconv.lib into Blender executive file, so I
add iconv at the end of
LLIBS = 'ws2_32 dxguid vfw32 winmm kernel32 user32 gdi32 comdlg32
advapi32 shell32 ole32 oleaut32 uuid'

2./cvsroot/bf-blender/blender/source/blender/src/SConscript
To enable ICONV.

3./cvsroot/bf-blender/blender/source/blender/src/filesel.c
I mainly modified this file
if some 'if' or 'switch-case' are added in, other languages will be supported

4./cvsroot/bf-blender/blender/source/blender/src/interface_draw.c
I modified this file to support intenational. broken(a name) told me. Thanks.

I think somebody can enhance it. Here I just give a suggestion for
native English coders. The code seems stable now.
