EDIT:
To clear the current user’s font cache, first quit all running applications (otherwise, you may see font oddities after using the command), then open Terminal (in Applications -> Utilities) and run this command:

sudo atsutil databases -removeOnce you’ve cleared the caches, you should stop and restart the ATS server with these commands:
$ atsutil server -shutdown$ atsutil server -pingIt will take a second or two for the server to restart, but when it does, you should be good to go. If anything still looks odd, a logout and login should take care of any lingering issues.
