Somehow the kerning does not work in waw when we add a fatha. On top the correct kerning and on the bottom the kerning does not apply.
Any ideas what is causing it?
The Kerning would need to have an IgnoreMarks flag. Which app version are you using, and how did you implement Kerning?
I am using the version 2.4 of Glyphs.
I applied as well as I would do in the latin but from right to left.
Can you try the latest version (that is 2.4.4)?
And make sure your Edit View is in RTL mode.
