Hey, I have currently begun the implementation of freetype for my job but come 
across the issue of unnecessary characters.

For various fonts it will present the rectangle for a glyph I assume it 
couldn't determine, but there are no errors and even the data is still filled 
in.

Is there a way I can skip these characters without potentially having a map of 
all fonts and the dimensions a rectangle would present (which is still not 
desirable as some characters may actually meet those dimensions)?
Thanks
