Issue with Diacritics/Harakat positions and placement and tested on 6 fonts

[bossxero]

Hello,

I have been trying to produce arabic text using the python reshaper but was unable to get the diacritics to show well in any of the text generated. I have tested with different fonts but it has not worked properly so far. I would be grateful if I could get some help from the community to resolve this issue. Please find the test code i have used and the generated image. I am using PIL to place the text on the image. As we can see in the image below, the diacritics often overlaps the letters or other symbols. The Shift_Harakat_Position did not solve the issue.

List of fonts which I tested are Amiri, Arabic Typesetting, Arial,NotoSansArabic, Traditional Arabic and Zekr Quran
