General Arabic Installation Question

[Ibrahim Shaame <ishaame at hispeed-sr dot ch>]

I have been trying to install Arabic on my machine but have not been 
very successful. When I get into KDE I just get squares instead of 
Arabic characters. I also get the same thing with XFCE (another window 
manager). I have fonts already installed and recognised by X (atleast 
some of them; when I use gedit I can select these fonts, and when I 
print fonts I can see Arabic fonts in the list). Could you please let me 
know how to solve this problem? Is there a file (config, maybe ) in the 
windows manager which determine the fonts to be displayed in their 
windows? I would like to use Arabic independent of any specific windows 
managers.

Thanks
