["hicham.dev" <hicham dot dev at menara dot ma>]

Hello
 
I am new in this mailing list, I don't know if i 'm at the right place 
to ask this,
I've changed some settings under KDE3.4.2 using "Desktop settings 
wizard" in Fedora Core 4 .
and now  arabic sites under firefox don't look right. the arabic 
characters are unlinked
I've tried to change the character enconding, it didn't solve the problem.

Thanks for your help
