I have this in self service, if memory serves, I think it is the command UTC uses.

Run Unix command 'atsutil databases -remove'

The I force a reboot.

Yep we run this and reboot.

#!/bin/sh
# Removes all user and system font caches
atsutil databases -remove
# Removes all user caches
atsutil databases -removeUser
# Stops the Font service
atsutil server -shutdown
# Starts the Font service
atsutil server -ping
