From a 2003 bug report on the Mac OS X Open Firmware utility:
If you used Open Firmware Password utility to create a password that contains the capital letter "U", your password will not be recognized during the startup process (when you try to access Startup Manager, for example).
How on earth did that bug creep in? (Thanks to Conrad for the pointer.)

Bet you a buck it's related to internationalization.
