On my Ubuntu 12.04 LTS, unwanted Asian language (I cant tell which) is set. Odd thing is I kept choosing English US all along, but I still get this garbage mixed in the icon definitions, Firefox icon is messed up, other arent, then top-left most menu description is gone. I saw this post
But the fix described there did not work for me. I looked in my .profile, .bashrc, /etc/profile, there are no language settings there.
