After installing Sierra and a number of other fonts from Google Web Fonts, I now see the 'question mark' against any list items either within the actual system UI and other applications such as Chrome.
Edit:
I have already attemped two possible solutions:
You can use TinkerTool to change the default system fonts and increase their size.
Mac OS X places installed fonts in the user's Library folder to differentiate between system fonts (located in /System/Library/Fonts), OS fonts (/Library/Fonts) and user installed fonts (/Users/~/Library/Fonts).
You can change this by open Font Book preferences (File>Preferences) and changing the "Default Install Location" option from User to Computer.
Hope this helps.

Forgot to mention - If you're not able to delete the font from Font Book, try removing it from the /Users/~/Library/Fonts directory and emptying the trash. Also, make sure it's not a font that is also in the /Library/Fonts directory (preinstalled).

Run
sudo atsutil databases -remove, then reboot.atsutil is the CLI for the font registration system. Resetting the database can help clear up errors like this. Also see Check mark disappeared from dropdowns.
