> Let alone exotic languages such as Urdu/Persian that are highly cursive and ascend upwards depending upon the length of the word

I've never heard about this. Where can I read more about it?

You can check the Pango's script gallery (GNOME project) [0] as showcase of their prowess to be able to render Persian/Urdu that is the most complex form of Arabic script.

Complexity comes from the fact that in Arabic, a single character can have at max 4 contextual shapes generally speaking. In Nastaleeq variation, a single character can have up 100s of contextual shapes depending upon where it appears in the word.
