Remove and rebuild font cache files on Mac OS X

During my previous investigation to determine why Mac OS X Leopard CPU usage spike up, I've read tips that said clearing up my font caches might help with the problem. So I've set out to search for tools to will help me to do this task, and stumble upon FontNuke.

FontNuke claims that the following symptoms might be due to corrupted fonts, and clearing the caches might fix it:

• Fonts which have been added to the system or activated with 3rd party software, do not show up in application font lists
• When multiple styles for a similar font family are active, the font displays as a different style then is selected (e.g.; Garamond-Bold is selected but displaying as Garamond-Italic)
• Text is garbled or random characters are inserted
• Text disappears entirely
• Applications stall or quit immediately after launch
• Fonts look correct on screen, but when printed:
• convert to Courier or other random fonts
• do not print at all, an error may be generated or nothing happens at all

So, if your Mac is displaying garbage, it might be a good idea to try this free software software. Be warned that a forced reboot happens after the caches have been cleared, so save all your files and close all programs before running this tool.
