Go to the Applications folder and start up the Font Book app and do File > Restore Standard Fonts and restart.

If that doesn't work, try a Safe Boot.


Best guess is font corruption at OS-level

Reinstall your current OS's latest combo updater - find it here & refine the search at top left for your actual current OS.
