// Character Complement Numbers
//
// The "Intellifont Unbound Scalable Font Header" (header) includes a
// 64 bit field (bytes 78-85) which contains the Character Complement
// number. For TrueType fonts, in the "15 Font Header for
// Scalable Fonts" (unbound), the Character Complement number is
// included in the accompanying "Font Data" section of the
// header.
// The Character Complement number identifies the symbol collections
// in the font. Each bit in this field corresponds to a symbol collection
// (not all bits are currently defined; refer to Appendix D in the PCL 5
// Comparison Guide).
//
// This 8-byte field works in conjunction with the Character Complement
// field in the header of a type 10 or 11 (unbound) font to determine the
// compatibility of a symbol set with an unbound font. These two fields
// identify the unbound fonts in the printer which contain the symbol
// collections required to build a symbol set. Refer to "Scalable
// Fonts" in Chapter 9, for a description of symbol collections and
// unbound fonts.
// Each bit in the field represents a specific collection. Setting a bit to 1
// indicates that collection is required; setting the bit to 0 indicates that
// collection is not required. (Bit 63 refers to the most significant bit of
// the first byte, and bit 0 refers to the least significant bit of the eight
// byte field.) The bit representations for the collections are shown
// below.
