Arabic font issues

[David Brodbeck]

Hopefully this isn't a FAQ.

I'm trying to figure out how to get UTF-8 Arabic text to display in  
Emacs 22.1.1.  I currently get hollow boxes instead, which makes me  
think it's a font issue, but I'm not sure how to correct it.  I do  
have X11 Arabic fonts installed.

I'm having this problem both on a RedHat Enterprise Linux 5 system  
and on a Debian Etch system, so it doesn't seem to be distribution- 
specific.  On the RedHat system I compiled Emacs from source; on the  
Debian system I used a package from http://emacs.orebokech.com.

Any pointers would be appreciated.  I tried doing a web search but  
mostly found references to doing it in Emacs 21.
