Yes, I see this also.  Strange, it sounds like we compose these two
characters, but the resulting grapheme cluster is incorrect.  I hope
Handa-san (CC'ed) could look into this.

This I don't see on my Windows machine.  Hebrew is displayed correctly
for me.  This is in 'emacs -Q", right?  If not, please try in "emacs -Q".

> I Linux I installed some additional packages two display arabic correctly. Maybe I have to install packages for windows - but wich? 

No additional packages are needed for Windows, the Uniscribe shaping
engine, which Emacs uses on Windows, supports everything.
