newspaper-o icon bug

[agostinocinelli]

Hi, I have a problem with the newspaper-o icon.
I'm using it in the TabBarController, I create an UIImage with that icon but the icon doesn't appear.
The same code works with other icons, infact i have 5 Tabs and i have 4 working icons.
Well, it worked once or twice at the beginning, but after few build-and-run the "newspaper-o" tab's icon disappeared forever. I experienced the same behaviour on the simulator and on my iphone 4s.
I deleted the otf files and downloaded them again, nothing changed.
Any ideas would be appreciated.
