That's because you should never use the U+FEFB glyph to type Arabic (or 
any glyph in those Unicode Arabic Presentation Forms blocks). the 
reason it's there is only for deprecate encodings. If you need the 
lam-alef ligature, the only good way is typing lam and next an alef.

What program are you using? Qt3/KDE3 doesn't do proper placement of the 
diacritics, Qt4 and Pango (I have version 1.18.2 here) display the 
glyphs correctly, OpenOffice.org seems to only have problems with 
putting vowels on the alef properly.

Try to update your Pango and see if the problem is fixed.
