why doesn’t want me to export? As if the program cannot distinguish between uppercase and lowercase letters. These are different letters. Likewise, the program does not see the difference. I click to edit “ę” and it opens a window “Ę”. Why is this happening?
Try to select all your glyphs and run Glyph > Update Glyph Info
That command is not available in Glyphs Mini.
The simplest way to is to find the uppercase glyphs in that list and add an underscore to the name and then remove it again.
Georg means that you can click on the glyph name to edit it. Then you add an underscore to the glyph name, save that name (Esc), then edit it again to remove the underscore.
This is easily done via a script, I don’t know whether those are possible in Glyphs Mini:
for layer in Font.selectedLayers:
glyph = layer.parent
glyph.name += "_"
glyph.name = glyph.name[:-1]
Usage: select all (uppercase) glyphs where this issue arises, then paste the code into Window > Macro Panel and click Run.
No scripts in Glyphs Mini.
