Hello everybody
I’ve been struggling with this all day.. I’m trying to edit a variable arabic font.. but whenever I try to preview it, and activate the ccmp Glyph composition feature.. the app crashes immediately..
Can any one help me with the please?
I tried to attach the crash report.. but I got an error message saying I’m not allowed since I’m a new user 
What version of Glyphs do you have?
And could you send me that file that I can have a look?
Hi George..
Thank you for your response.
I’me using version 3.3.1
I’ve sent you a link to download the font file as I’m unable to attache it here.
Thank you so much for your help
The font you sent is not a variable font, just a plain old OpenType font.
What string did you have in the edit view when you activated the feature?
