I generated OTF fonts with arabic, but all the kerning for the arabic part is missing, while the latin is still there.
I test my fonts by exporting them directly to the fonts folder in the inDesign folder, so I don’t think its cache.
I’m sure I’m missing something here.
There is a problem with your file. A lot of the glyphs don’t have unicodes assigned. I don’t know how you managed to do that. Select all glyphs and run Glyph > Update Glyph Info. (That will give you an error with a duplicate Tcommaaccent/tcommaaccent. Rename one of each to Tcedilla/tcedilla.)
The glyphs without unicodes came from Fontlab, I started the font there. I may have lost the unicode values in the process of renaming glyphs to meet Glyphs namings, using scripts.
I got the kerning working fine now, btw.
Thank you for the the tip.
