Punctuations Not Exporting Properly

Currently trying to build out the punctuation in a font I’m making and I keep running into this issue whenever I run a test install. For reference, I am testing my install using Adobe Illustrator.

What happens is that my apostrophe—quote single—is turning into my asterisk. What would a possible solution for this be?

Thank you!

That seem like a cache problem. Do you follow this: Testing your fonts in Adobe apps | Glyphs ?

Ah—You were correct on this! I will follow that link for future testing.

Thank you!
