UNICODE WITH MS-IME

UNICODE WITH MS-IME

[-- Attachment #1.1: Type: text/plain, Size: 4302 bytes --]

I must work on windows and with multi language.
I use windows IME to input multi language.
so emacs must accept unicode MS-IME.

I modified emacs23 to accept unicode MS-IME string.
I only known a little C and don't know emacs construction.
so this patch may have many bugs.
I post it here.hope somebody add unicode ime support in emacs23

I maintain the IME-patch with some w32 original features for
emacs-csv and emacs-unicode2.
The original version which was written by MIYOSHI Masayoshi
for emacs21 was based on Meadow which is another emacs for w32.

http://homepage3.nifty.com/y3tk/emacs/emacs-unicode-cvs-20070314-IME.patch

Please try it.
After release emacs22 I am planning to post it in this list.
