As a moderation note:
I have changed the title from “Glyphs typeset along a path” to " How to typeset glyphs along a path?".
The question guidelines recommend this:
Good titles are questions you would ask your friend about Typst.
For this question, you were already there: it was easy to reformulate the title into a question so that’s what I did.
Also remember to mark the answer that helped you resolve your problem as a Solution using the
