>> Thanks, this bug is now fixed. But there is something wrong with the two diacritics (short vowels): ARABIC KASRA and ARABIC KASRATAN. They should appear UNDER the letters, not IN or OVER them.
>>
>> Try a-A [Sheen-Kasra] or a-S [Sheen-Kasratan] or d-S [Ya-Kasratan].
>> But h-S or m-S has the correct form. (?)
> 
> This happened because w32uniscribe.c didn't reverse the sign of the
> y-offsets returned by the Uniscribe shaper. This reversal is
> necessary because the Y axes in font definition coordinates and in
> Emacs screen coordinates point in opposite directions.
> 
> I see that ftfont.c consistently reverses the sign of y-offsets,
> probably for the same reason.
> 
> Fixed in trunk revision 109876. Please test.
> 
> P.S. This bug affected all complex scripts, not just RTL or Arabic.
