Fonts don't export from 3.2, no error message

I’ve built Glyphs files from the IntelOne Mono UFOs, fixed some interpolation compatibility issues, and set up the instances. However, from Glyphs 3.2, I can’t export the fonts, neither OTF nor TTF. There is no error message, and no exported fonts. It works from Glyphs 3.1.

IntelOneMono.zip (153.5 KB)

There is an invisible “stylenames” property in the font settings. I fixed it that it shows all unsupported keys. But not only was it not show, but also was used nevertheless. So it was producing invalid instance names. You should have gotten an error about this.

For now remove those lines from the file:

{
key = styleNames;
values = (
{
language = ENG;
value = Light;
}
);
}
