I repectfully disagree with Werner's statement about these broken fonts. Blue 
zones are simply a declaration of font properties that the designer specifies. 
It is up to the hint interpreter to decide how to use that data. For example, 
there is a heuristic in the Adobe CFF interpreter that synthesizes charstring 
hints from blue zone data.
