public class T2TDOEncoding
extends T2TDONumber

Encoding.

Note: The encoding table in a CFF font is indexed by glyph index; the first encoded glyph index is 1.

Encoding data is located via the offset operand to the Encoding operator in the Top DICT. Only one Encoding operator can be specified per font except for CIDFonts which specify no encoding. A glyph's encoding is specified by a 1-byte code that permits values in the range 0-255. Each encoding is described by a format-type identifier byte followed by format-specific data. Two formats are currently defined.
