"Can't convert to compatible TrueType curves. Glyph 'S' is not compatible"


Hi everyone,

I have some problems when I wanna export my variable font:
“Can’t convert to compatible TrueType curves. Glyph ‘S’ is not compatible”

It happen with several glyphs. I corrected the path direction and I has tidy up paths. But nothing changes. How can I fix it?
I really don’t know what to do…



What version of Glyphs do you have?

Did you read this: https://glyphsapp.com/tutorials/multiple-masters-part-2-keeping-your-outlines-compatible


No I didn’t read it but I will :smiley:

I have the Version 2.5.1 (1141)


Try the latest beta please. Go to Glyphs > Preferences > Updates, activate both checkboxes and press the Update button.


When I go there, it said I ever had the latest version.


Can you add a Enforce Compatibility Check parameter to the font? That should highlight the glyphs that are not compatible. If that doesn’t help, could you send me the file?


Yes of course, how can I send it to you?


You can send us the .glyphs file to support (at) (this website without www).


Done! :slight_smile:


As I said. Adding the Enforce Compatibility Check parameter shows that the “S” is not compatible (you might need to close and open the file to get the update).

The “petit” “S” has one segment a curve and two missing lines.
