Could he have made a mistake?
What exactly is the problem?
About OpenType feature code.
Please describe the problem.
It’s impossible to guess, especially if you’re unable to read Chinese (there is no way to translate your screenshots properly).
It seems to know glyphs very well and can answer any questions. You can try it here: https://claude.ai/
So what’s the problem? Yes, Claude is very good.
OpenType feature code is difficult for me, so I asked it, and the result was very surprising. It even guessed that I was using Glyphs.
It’s amazing.
Cannot help you with Claude. If you want to know more about OpenType features, you’ll find ample documentation in the tutorials and the handbook. Closing this thread.
