OS X users: puzzled by that long list of pesky system fonts that pollute your font menu? Learn about whence they come and what languages they speak from Apple’s Mac OS X 10.3 Fonts list. [Update: OS X 10.4 Fonts list]
The page also indicates which fonts can be disabled to make that menu just a little more tolerable. What isn’t mentioned is that font managers like FontAgent Pro (my favorite) can disable some of those “essential” fonts. Just be careful.
