CCLabelBMFont unsupported characters - feature request

Hi,

I’m working with the bitmap font class. I have the situation where the user introduces text to the game using the keyboard. What if he types a character that is not supported by my bitmapfont? The game crashes…

most game engines allow to setup a default character, so when some of the characters is not included in the bitmapfont, it is replaced by this default character. As far as I know cocos2d-x doesn’t support this feature.
