change outgoing news charset

[William Xu]

Hi all,

I already have (prefer-coding-system 'utf-8) in .emacs. What should i do
if i want to use a different charset(actually 'gb2312) when sending
news? I tried this, (setq mm-coding-system-priorities '(gb2312 utf-8)),
but then this error occurs,

Sending news via news.newsfan.net using nntp...  441 Feedrule: line 79:
Uuencode��ʽ���Ҳ�Ҫ���ֶν��б��
Couldn't send message via news: 441 Feedrule: line 79:
Uuencode��ʽ���Ҳ�Ҫ���ֶν��б��

Also, tried this, still no luck, though.

(setq mm-body-charset-encoding-alist
      '((gb2312 . 7bit)
        (iso-2022-jp . 7bit)
        (iso-2022-jp-2 . 7bit)
        (utf-16 . base64)
        (utf-16be . base64)
        (utf-16le . base64)))

Any ideas?
