I have set the fsType of a font to ‘Installable’, but when exporting a TTF font out of Glyphs 3, it sets the OS/2.fsType as “0x0001”. Per the specification, “Installable” should be set as “0x0000”.
I added a note to look at fsType when I was reviewing codePageRanges, yesterday. That issue will be fixed soon.
I fixed it.
