Example using NotoNastaliqUrdu font
Description:
Nastaliq fonts, for example "Noto Nastaliq Urdu" and "IranNastaliq" are
different from Normal Arabic/Persian/Urdu fonts in the way Kashidas are
implemented.
This example uses "Noto Nastaliq Urdu" font which does not use kashida at all.
IranNastaliq font works with kashida, but they are implemented as ligatures.
Using the horizontal lines as kashidas with Nastaliq fonts causes rendering
defects.
Steps to Reproduce:
1. Install NotoNastaliqUrdu font
2. Open the example file
Actual Results:
Bad black lines are visible in the output. Kashida is not suitable for Nastaliq
font.
Expected Results:
No black lines should be visible in the output. Also, the spacing of the
characters should not be very big.
Reproducible: Always
User Profile Reset: No
