CJK on mutt

[Lucifer]

I plan to move to mutt as my email client.  However, I find the mutt of cygwin can not handle CJK (Chinese, Japanese, Korean) characters correctly -- they are displayed as "????"s.  Since I am running cygwin on a Simplified Chinese version of Windows 2000 box, I put the following in my .muttrc:

set locale="zh_CN"
charset-hook !utf-8 gb2312

but nothing changed, ????s are still ????s.

Anyone here use CJK too?  Can you resolve this problem?
