I’ve been having some problems generally today, but this in particular reminds me of something I’ve seen before in another font.
Every type of file has a way it appears as a preview in Finder (images show up as themselves, zip files show up as a piece of paper with a zipper, etc.), and font files show up as these characters set in the selected font:
In other words: there’s an extra 1 between the A and the B, the a is replaced with a dieresis, the e is replaced with a cedilla, and everything but the dot of the i is gone.
Can anyone help me figure out what’s going on, and if it’s an issue?
That must be your .glyphs file. Your .otf or .ttf should be fine.
I believe the preview plugin for .glyphs file has not been updated for Glyphs 2 and its advanced components, which is why the preview is partly glitched.
