If using tcsh and set LANG to ja*, the output messages by tcsh are not correctly printed out (in Japanese). example: $ tcsh $ setenv LANG ja_JP.eucJP; help help: \245\263\245\336\245\363\245\311\244\254\270\253\244\304\244\253\244\352\244\336\244\273\244\363. $ setenv LANG C; help help: Command not found.
I don't get ANY japanese even when the locale is set. What installation option did you choose?
