Isolate arabic glyphs are not loaded


Arabic font that I’ve created with Glyphapp everywhere works properly but in the Kindle book reader isolate Arabic glyphs are not loaded. (In this picture you can see what happened)

What is the problem?


Can you double check the character stream with UnicodeChecker?


I started the project from an empty file in Glyphsapp, and I’ve added all Arabic glyphs from the “Glyph info window” to the font.
Unicode glyphs are correct.
I think this is a particular problem in the type of open-type table.
Arabic fonts, which were previously made in other software, did not have this problem.


Can you send me the .glyphs file and the text?


Yes . I sent you a font and e-book


I added the .isol to Isolate letters Unicode, and the problem with that letter was solved.
For example (dal-ar > dal-ar.isol) this caused (062F > FEA9)
Why does the glyphsapp do not add .isol when generate these glyphs ?!
Do I need to do this manually for all isolated letters?


It is thinkable that the default character is not drawn as isolated.

You can batch process all letters: Duplicate the glyphs (Cmd-D), find and replace (Cmd-Shift-F) the suffix with .isol.


I think it would be better for Glyphsapp to add .isol glyphs like .init .medi .fina when generate arabic glyphs.


You can also add 2 Unicode’s into one glyph instead of duplicating the isolated letters.
And make sure that you updated the features every time.


Yes, I did it exactly.
