I received a bug report from a Chinese user complaining that Emacs 22
wants to use a Japanese font to display a character from the Chinese
alphabet, even if the language environment is set to something Chinese
(in this case, Chinese-GB).
My guess is that the character is identical in Chinese and Japanese
(kanji) alphabets and that Emacs just uses the "best fitting" font,
which isn't installed on this user's workstation. Apparently,
(list-charset-chars 'chinese-gb2312) correctly shows the character, but
the font isn't selected when displaying a regular buffer.
Is that a bug or a configuration problem? I'm not really knowledgeable
about this stuff, can someone enlighten me?

In any Chinese-XXX lang. env., if that character is (0x4A4A of GB2312) encoded in UTF-8, Emacs correctly decodes it into chinese-gb charset. So, my question is how he got that character in Emacs buffer. One possibility is that he cut&pasted it from the other application and that application sent that character encoded in compound-text while designating JISX0212. In that case, Emacs surely decodes it into japanese-jisx0212, but that is a correct behaviour. (setq x-select-request-type '(UTF8_STRING COMPOUND-TEXT)) forces Emacs to ask the other application to send a selection data in utf-8 if possible. So, this setting will work for him. --- Kenichi Handa handa@m17n.org ^ permalink raw reply [flat|nested] 6+ messages in thread

The default is to prefer JIS. If you prefer Chinese, why don't you use, for instance, zh_CN.UTF-8? By the way, you wrote: > I prefer it is bug, becase this bug still happen even when I use > (set-language-environment "Chinese-GB"). You must change the lang. env. before you read a UTF-8 file. Have you tried it? I agree that it's not good that saving and reading with the same coding system doesn't give you the same character. But, that is the limitation of the current Emacs, and can't be solved easily. If you really have to be in English language environment but prefer Chinese, please try this in your .emacs. (set-language-environment "Chinese-GB") (set-language-environment "English") --- Kenichi Handa handa@m17n.org ^ permalink raw reply [flat|nested] 6+ messages in thread
