How to change the locale of Slackware 8.1 to zh_CN.GB2312

gWuBi can't work.
This is the wrong information:
bash-2.05a# gWuBi
Your locale (en_US) may be not set to Chinese, I may not work properly!
Font locale not supported! Using zh_CN
XMODIFIERS is not set!

bash-2.05a# locale
LANG=en_US
LC_CTYPE="OSIX"
LC_NUMERIC="OSIX"
LC_TIME="OSIX"
LC_COLLATE="OSIX"
LC_MONETARY="OSIX"
LC_MESSAGES="OSIX"
LC_PAPER="OSIX"
LC_NAME="OSIX"
LC_ADDRESS="OSIX"
LC_TELEPHONE="OSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=POSIX
bash-2.05a#

If I can change locale to zh_CN,will gWuBi work correctly?
