Chinese input method in English Ubuntu system (Take SCIM as example)

1.Install the Chinese language support: System/Administration/Language support/Install&Remove Language--------Choose Chinese to install.
2.Install the SCIM-pinyin input method. Anyother input method is allowed (e.g. Wubi), choose your favorate one.
3.sudo gedit /etc/environment 把LANG = en_US （其他语言不同）改为 LANG=en_US.UTF-8 或者 LANG=zh_CN.UTF-8, For example:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
LANGUAGE="en_CA:en"
LANG="en_CA.UTF-8"
4./etc/X11/Xsession.d/里新建一个名叫95xinput的文件: sudo gedit /etc/X11/Xsession.d/95xinput; 在其中添加如下内容：
/usr/bin/scim -d
export XMODIFIERS=@im=SCIM # 设置应用于所有的X应用程序
export GTK_IM_MODULE=scim # 设置GTK的默认输入
export QT_IM_MODULE=scim #设置QT的默认输入
