Sure, why not? They could possibly develop into letters. Much will
depend on the conlang in question and its writing system.

The 'rough breathing mark' becomes a letter (for the /h/ sound) in
Loucarian, for example.

People often use the apostrophe to represent the letter for the glottal

The only question becomes: why would you use the star or the dollar sign
or whatever for letters in one of your (presumably Yemoran?) conlangs?
You'd probably want to come up with a Yemoran system of writing, rather
than use the English one...
