Numbers + FontAwesome Don't Render Correctly

[Vortec4800]

I don't know if this is really an issue with BButton as much as it's with FontAwesome, but I wasn't sure where I would bring this up in that case. It seems when using an icon along with text, numbers in the text get rendered strangely and without a shadow. Is this an issue with the FA font itself or something that can be fixed?

Seems to be the font if you ask me. Maybe you could write the creator of fontAwesome:
