In Powerpoint for Mac 2011, when using any of the 'Nilland' fonts a character that looks like a '1" (but isn't) is being added to the end of any text. I can't select it and so can't get rid of it. I've had no other problems with these fonts in other Office products (e.g. Word) or other applications such as Illustrator. Anyone have any idea how to fix this? It's very frustrating!
