Persian Text Rendering Problem within iOS 11's new font #134

Hi! hoping that you're great.

As of iOS 11, a new font has been introduced for Persian. The font is okay across all apps except Telegram. If you look:

If you look closely dots are not rendered correctly. Some of them are higher than they should be.

Given the fact that no other app that I have has the same problem, it means you're using some special rendering system and this font is not good with that special system.

These are the characters that I found are troubling the render. And these are the test cases I think you should investigate:

ققق
ففف
غغغ
خخخ
تت
ثث
نن
