Please visit my forum at the following link:

I used SMF 2.0 Beta 4.0 p.
the forum is still new and in Arabic; you will notice that the posts I wrote as Administrator are showing correctly but the posts written by others in Arabic on reply to my post are not showing correctly.
I noticed also the same problem when I register with a user name written in Arabic then the forum changes this name unexpectedly and that user becomes unable to log in.
Please help with a convenient solution ASAP as my forum should be published tomorrow.
I'd say,you should better ask that in Arabic Support Board
العربية (Arabic) (http://www.simplemachines.org/community/index.php?board=71.0)
