Problem with showing arabic script

[Yaser]

Hello All,
I compiled Wine-0.9 with ICU to support BiDi. And I used LC_CTYPE to  
choose the appropriate character map.
The Arbic letters are shown in the right order (from right to left), but  
they are shown separated and not connected.
Any Idea to fix this problem?

Thank you in advance.
Yaser..
