Chosen solution

I had the same problem and the fix was to go to font book. If your not sure where this is search for it. From there have osx validate all your fonts. This should find the fonts that have errors in them. Delete the messed up fonts. In my case I have ~1,700 fonts and 20 had errors. Deleted the ones with errors and this fixed a font issue within Firefox, Outlook and Adobe CS5.
