When I install the Debian, I choose the language to Chinese. After installation, I found that the menu is displayed in Chinese, even in the terminal the promote are written in Chinese.
I want the interface language change back to English, however it should not destroy my settings, eg. my input method, and when display Chinese characters, it will not display it as squares or some other random characters. Here is some locale output:
~$ env | grep LANG
LANG=en_US.UTF-8
GDM_LANG=zh_CN.utf8
LANGUAGE=zh_CN:zh
~$ locale -a
C
C.UTF-8
en_US.utf8
POSIX
zh_CN.utf8
In my /etc/locale.gen
I commented off the en_US.utf8
and zh_CN.utf8
