1) create a BMessage for storing font family data (hereafter, the font message)</P>

Supported character mappings are Windows and Apple Unicode, Windows symbol, and Apple Roman character mappings, in order of preference from first to last.</P>
These return a copy of a pointer to the system-wide ServerFont objects which represent the appropriate system font settings. It is the responsibility of the caller to delete the object returned. NULL is returned if no setting has been set for a particular system font.</P>
The system fonts settings may be set via these calls by specifying the family, style, and size. They return true if everything worked out ok and false if not. Settings are not changed if false is returned.</P>
