spotted character set error

Spotted a bug in SkySafari 6 Plus. When I turned on the label option for the FOV circle, it appeared as:

0.5?

i.e. 0.5 with a question mark.

That looks like a font or character set issue with the degree symbol! 

That's a very peculiar error. 

Wow. That's kind of an important thing.

Once again shows they did little testing or checking.
