At least for CJK characters included in legacy character sets (e.g. JISX0208, GB2312, etc), iso-2022-7bit is still better than utf-8 if we concern font selection. > Is it possible > to improve the UTF-8 support in Emacs since most files use it nowadays? For that, we must use language tags, but they are strongly discouraged by Unicode. Unicode doesn't concern font selection problem. It says that it is a task of higher level information, for instance, that is provided by XML's language tag. --- Kenichi Handa handa@m17n.org
