Okay, so I've got Japanese locales sorted, an IME sorted, I can see and type in Japanese with no issue. Apart from on title bars and in my menu -- it's just squares there. I contemplated that it may be because of the system font being set to something which doesn't support all the unicode characters (though I don't know if it does or not). So if anyone could kindly tell me how to set the system font (I'm using arch by the way, with fluxbox) or any way to fix this, I'll be most grateful.
Thanks.Fixed it myself.
EDIT: I changed my fonts using
this to one which supported the unicode characters.
