When I add Custom Parameter
fsType and leave its value at the default Installable, then try to export to UFO, I get the following error:
The resulting UFO is missing both the the lib.plist and fontinfo.plist files.
Values other than Installable seem to work OK.
Alternatively, if I add
openTypeOS2Type and leave its value as Installable, the UFO export works.
I’m using Glyphs Version 2.4.2 (1038)
