I don't quite understand the above. But one problem that
occurs to me is that if the text you were passing to
Pango was encoded in presentation forms like using
U+FB52 instead of U+06B2 for beh, then Pango wouldn't
shape it into connected arabic text.

I just filed 

 http://bugzilla.gnome.org/show_bug.cgi?id=110896

For improving the handling of presentation forms in
Pango. But generally, text fed to Pango shouldn't use the
presentation forms.
