/* \class OXML_FontManager
 * \brief This class handles all the font-related activities.
 * OXML_FontManager has two main purposes.  The first is to keep track of mappings
 * between a character range and a specific script.  The character range is either
 * ASCII, East-Asian, Complex, or H-ANSI.  The script is a string in the ISO-15924
 * standard format.
 * The second purpose of OXML_FontManager is to analyze a font face name and validate
 * it against the document's FontTable part to ensure that the proper font face is
 * used (this is not yet implemented).
