Diacritics in Nastaliq/Nastaleeq

Is there anyway to fix positioning of diacritics in Nastaleeq. Normally, with changes in the glyph shapes, diacritics mess up. Avoiding their use is not always possible. Any guidance would be a favor.

Use OpenType GPOS mark anchors, that should give you enough control over placement of "diacritics" on any glyph.

Maryamsoft.com recognized the fallacy of the mark-positioning notion and cleared the air on that score:

This is a kerning issue. You need to provide kerning between the word that contains the Yeh Barri and the "Space" character that comes before the word, as well as the letters that do not connect on the left like Alef.fina, Dal, Reh, and Waw.

There may be easier ways to do this, but here is one approach to the problem. I make groups of the letters, or letter combinations, that come before Yeh Barri based on how wide they are. When the width of such letters, or groups of letters, is more than the Yeh Barri tail extension to the right, I provide appropriate kerning as needed between the first of the connecting letters and the Space character that comes before it.

The number of such kerning lookups, the type of adjustment, and what context to use in these lookups, will depend on the particular design of your font.
