Ok so I’m new to Apple.. and I have a new MacBook Pro.. bought it last year. I am receiving text in emails and other pages in blocked question marks?? No letters! What do I do??

It is a font problem—

Restore fonts that came with your Mac using Font Book ...

Does not fix the problem. What's the next right answer? If I copy the "question mark" text and place it in a text editor… it's Georgia. Georgia is apparently fine according to my Font Book.
