I'm not used to setting chinese suport but for japanese, I add following lines in /etc/profile:
Code:
export LC_CTYPE=ja_JP
So if my guess is correct, you should add:
Code:
export LC_CTYPE=zh_CN
to the /etc/profile.
You could also try the following:
zh_CN
zh_CN.gb18030
zh_CN.gb2312
zh_CN.gbk
zh_CN.utf8
zh_HK
zh_HK.big5hkscs
zh_HK.utf8
zh_TW
zh_TW.big5
zh_TW.euctw
zh_TW.utf8
from 'locale -a' command.
