There was a problem compiling TrueType instructions for glyph: .notdef

I am having a problem exporting the font. I deleted the glyph but still not working. 04

Done.

I’m seeing this problem in Version 2.5.2 (1153). Deleted the .notdef glyph but the error is still showing. Was there a fix or workaround?

I don’t remember. Can you try the latest cutting edge version or send me the file?

Sent you the Glyphs file by email :slight_smile:

The problem in your case is that you have stored TrueType instructions (in Font Info > Masters; Prep Table Assembly, Fpgm Table Assembly, CVT Table). Remove those and it should work.
I added an error message to tell the user about that.

Thank you! Removing those parameters fixed the problem.
