Glyphs does support kerning for Arabic fonts. And it does so for years now. As I said elsewhere, the 2.6 version has a but with it. It is fixed with the cutting edge version that will be release in the next few days.


ok, i’ll use 2.6, i love glyphs app george, thank you for that dear.

Georg, I have a problem with updates and no articles or solution until now!
I use 2.6 actually but I should join the website and download it and uninstall the old one and it takes time so any article solution or video … etc?
