[LUAU] X Input Methods

[MonMotha]

Yeah, I actually have a question for once :)

I'm not really an X guy, so I wouldn't even know where to begin on this.

I'm interested in setting up alternate input methods to allow me to type 
characters that aren't on my keyboard in X.  I'm mostly interested in the 
greek characters as well as Katakana from Japanese (and if I get Hirigana 
and Kanji as a bonus, so be it).

No distro specific solutions are allowed (other than maybe Debian if you 
must, though I'd prefer to keep it distro neutral so I could do it on 
another distro if I had to).  Any software that Debian has a package for 
(which is pretty much everything) can be used (so things like the kana 
manager), but I need to know the actual config changes that need to be made.
