Hi alfaifi,

The editor just uses the standard Windows textbox.  If Ararbic characters aren't displayed properly, then that would probably be because you haven't installed the proper character sets for your system.  Unfortunately, I can't help you much, since all I use is English :P and RCO Editor isn't responsible for the problem.

I would believe that Arabic characters won't work in some other programs which use the standard textbox too - right?  Perhaps look in your Windows CD and see if you can install it from there, or check Internet Explorer's encoding options.

Good luck!
