Has anyone else noticed this issue?
I have an ø and Ø which have alternate shapes. They both swap to alternative layer InDesign, Samsa, Wakamaifondue but not in Illustrator (latest version 2023, 27.1.1) the original layer doesn’t swap.
Illustrator but or font bug?
When it works everywhere else it is more likely a illustrator bug (one of the many).
OK Thanks Georg
