Hi Stephen
or modify your /etc/sysconfig/i18n or ~/.i18n and restart your X.
$ cat /etc/sysconfig/i18n LANG="en_US.iso885915" SUPPORTED="en_US.iso885915:en_US:en" SYSFONT="lat0-sun16" SYSFONTACM="iso15"
If you want to use zh_TW.UTF-8 on system wide you should change LANG=zh_TW.UTF-8, if not, you can put LANG=zh_TW.UTF-8 into your ~/.i18n
$ cat /home/satimis/.i18n XIM=iiimf-le-xcin
It would be: XIM=htt
Regards, Leon
