Having an odd issue. My dock is showing these strange red icons where normal numerical notifications should be. For example, Thunderbird will display a 3 when I have 3 new messages, but instead it is showing this red A? icon. This happens with all the apps in my dock that display a notification.
See attached screen shot:
Notice the Thunderbird icon at the top and the Printer icon at the bottom.
Anyway to get my standard notifications back?

This looks like it might be a problem with a system font. Try this...
/Applications
)If any fonts are corrupt, this method should alert you to the problem.
