Hello, Rainer,
Thank you for your response.
No, they’re not:
Ä (upper): U+00C4
ä (lower): U+00E4
Ö (upper): U+00D6
ö (lower): U+00F6
Ü (upper): U+00DC
ü (lower): U+00FC
ẞ (upper): U+1E9E
ß (lower): U+00DF
This matches the unicode in Glyphs Mini which is why this error message is so surprising. Could it be that the function for export compares those less standard glyphs with the name written and either capitalizes them or turns them in snake case and then compares the names if the glyph exists twice? Sorry, I am also a developer, so this is really interesting to me. Am I a DAU or is it a bug?
Best,
Hi Sebastian,
I did as you asked and noticed something additionally curious I have missed before.
I have two versions of the ß. The lower version which is very known and the less known upper version. In the “All Glyphs” section, you see all of them, but when you go to the language section, you only see the lower version.
Hope this helps.
BTW, I use a MacBook Pro with M1 Pro chip and Sonoma 14.5 and Glyphs Mini via SetApp.
Maybe it’s not a problem for all devices?
