What are symbols like that called?

I'm writing a novel and want interesting sounds without names like "Cardone-iie-o"

-Thanks!

Wing Dings.

Diacritic marks and phonetic transcriptions.

Yup, that's the generic term.

The individual marks have specific terms like cedilla and umlaut (only ones I can remember off the top of my head)

Just make sure you pick the mark that gives the accent you want for the name. Otherwise, when your thinking tomayto, they reader might be reading tomahto

You say tomayto, I say Heinz ketchup.

Haha, thanks. What do you mean CCNA? I was just going to find out how to pronounce each one.

They're called annoying.
