I'm not very fond if Scheherazade as it has many wrong glyphs (most of
the Quranic glyphs are completely wrong) and it doesn't even have an الله
ligature, which most Arabic users won't accept. I was experimenting with
a modified version that fixes those issues, but I gave up since the font
lacks any contextual forms but the basic four ones and extending the
font the way it is designed proved to be cumbersome and very error
prone.

If it is needed, I can clean the font and provide it to be included in
the minimal distribution temporarily, as I hope that we'll have a viable
alternative by the end of this year.

Regards,
 Khaled
