An unknown error has occurred

Hi, I’m trying to export the Glyphs file here:

as TTF. After a short time the export ends with the message “An unknown Error has occured”. The export fails.

Glyphs version is 2.3.1 (919)

I fixed it. Add one horizontal stem or a zone to circumvent the problem for now.

That works, thanks!

Howzit Georg, i’m quite new to Glyphs app and i don’t know how to “Add one horizontal stem or a zone” :slight_smile: Please help.

  1. Please read the Handbook chapter about PostScript hinting.
  2. Read these tutorials:
