How to clear font caches in Leopard. As you use various fonts in OS X, the system caches font data, to make future access faster.
However, there’s also the possibility that those caches may get corrupted, which can cause all sorts of interesting problems. One common symptom of corrupted font caches is seeing strange and overlapping characters in whatever application happens to be accessing the font with a corrupted cache. Prior to OS X 10.5, all font caches resided in the top-level Library -> Caches folder, in a file named com.apple.ATS. If you suspected a corrupted font cache, you just had to trash that file, then logout and login, and the problem would hopefully be gone.
That all changed in 10.5, however, as font caches are now created for each user, and stored in a subfolder buried in the /var -> folders directory. Please note that you do not need to do this regularly—in fact, I advise not using this hint unless you’re having a problem that you specifically suspect is related to a corrupted font cache.

Library Subfolder of Your Mountain Lion Home Folder. The invisible Library subfolder of your Mountain Lion Home folder is the repository of everything that OS X needs to customize your Mac to your tastes.
If you want to add something to a Library folder, it’s usually best to add it to your Home/Library folder. You won’t spend much time (if any) adding things to the Library folder or moving them around within it, and that’s probably why it’s now hidden from sight. Be cautious with all Library folders. OS X is very persnickety about how the folders and files within it are organized. You can add items to and remove items safely from most Public or Home Library folders, but leave the folders themselves alone.
