According to: http://www.isi.edu/in-notes/iana/assignments/character-sets
"cn-gb" is not an official registration. The prefered mime-charset is "gb2312", not "cn-gb". Some popular mail client such as "Mozilla-thunderbird" or "Emacs Mew" don't recognize "cn-gb" charset, and the messages don't display properly. This bug had been fixed in the main branch, but was somehow reintroduced in the emacs-unicode-2 branch. ---------------------------------------------------------------- *** chinese.el 2004-10-04 20:09:55.000000000 +0800 --- chinese.el.new 2005-06-04 02:45:48.642246024 +0800 *************** *** 75,86 **** ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (define-coding-system 'chinese-iso-8bit !
