I am using Anki (Version 2.1.65 (aa9a734f), Python 3.9.15 Qt 6.5.0 PyQt 6.5.0) on Debian 12.
I am trying to create cards with the Noto Nastaliq Urdu font. This font is installed on my OS and works as it should, diacritical marks included. In Libre Office Writer I can, for example, select my Urdu keyboard, select the Noto Nastaliq Urdu font, type “Z” and see a diacritical mark.
When I try the same when editing a card in Anki, I just get " "َ (a little white box). However, when I study, the diacritical mark is there - so it works in principle, just not everywhere apparently. This makes it a bit hard to type cards, as I have to do this blindly and then verify whether they are correct when studying.
Is there a way to enable diacritical marks in the card editor?
