It looks like I can’t add glyphs with a Python command in Glyphs 2: Glyphs.font.glyphs.append(GSGlyph('dcaron'))
No matter what I put as the first parameter, Glyphs creates a newGlyph without unicode. This also happens on a newly created font. My Glyphs version is 2.6.8 (1361). Can you please see if you can reproduce this?
