How to get Greek input in a Gtk+ 2.2 program?

[Preben Randhol <randhol+gtk pvv org>]

Hi

I have been using a program called xgrk to switch to Greek keyboard in
order to write Greek text. However now with Gtk+ 2.x and UTF8 support
and all I wonder how do one switch keyboards now? If I use xgrk now I
get latin7 input so there are no Greek letters only junk in the Entry
box. However if I use the yudit unicode editor and cut and paste from it
a greek text it is shown correctly as yudit uses UTF8. So I guess one
need a program that produces UTF8 characters? Are there any keyboard
switcher that does this for Linux? And does anybody know if the keyboard
switcher on Microsoft Windows works with Gtk 2.x?

I'm asking as I'm making a couple of programs that will have mixed
language input, so I need to know how to design my program.

Thanks in advance.
