iTunes Foreign Font?

Hey I'm not sure what I did, but some how I managed to change the font type of iTunes to some foreign font.

Any clues on how to get this back to normal?

Any help would be great.

Thanks

 

I just figured out what I did, I installed new fonts last night that I brought over from a Windows machine. I didn't install any of the fonts with errors or warnings.

Anyways I tried cleaning the font cache using ONYX and restarted to find that the text was back to english characters but seemed off and was bold, I also found out that Firefox was affected. I decided to run the font cache cleaner again to see if it could put back the original font but now I'm back to the foreign font.

Any way I could find out which is the default font and reinstall it?

Thanks
