Hi all,

I'm using 21.5-b25 (in WinXP), compiled with MULE=1
I'm able to read in UNICODE files containing CJK (asian) character
and I seemingly can type with CJK within XEmacs too

However, the problem is, after I saved the file, closed it, and then 
opened it again, I found all the CJK characters I typed in were lost: only 
the ANSI characters that I've typed in have been saved

Please help me what I have done wrong
Thank you very much!

Regards,

       Tsun
