Sanely Rebuild Corrupt Font Caches on OS X

For Leopard, at least:

# Clear user font caches
$ atsutil databases -removeUser

# And system cache
$ sudo atsutil databases -remove

# Restart the ATS server
$ atsutil server -shutdown
ATSServer shutdown
$ atsutil server -ping
ATSServer is running

# Check for filesystem activity (this is just generally cool)
$ sudo fs_usage | grep ATS

You might possibly still need to restart applications, log out and back in, or restart completely. Thanks to the fine people on this thread.
