I have three problems:
First:
Photopost is not accepting Arabic chars in new usernames

.
Second:
The board should be right-to-left but it is the opposite (ie left-to-right)

.
Third:
The Arabic charachters in the admin cp page only when I click on edit categories and also after selecting a cetegory then editing it, show, for example, as: ÇáÓíÇÑÇÊ instead of السيارات ..

. (there is no problem in viewing it in the main classifieds page).
Any advice will very much be appreciated

.
