   *   A structure modeling a custom encoding.
   *
   * @fields:
   *   num_chars ::
   *     The number of character codes in the encoding.  Usually 256.
   *
   *   code_first ::
   *     The lowest valid character code in the encoding.
   *
   *   code_last ::
   *     The highest valid character code in the encoding + 1. When equal to
   *     code_first there are no valid character codes.
   *
   *   char_index ::
   *     An array of corresponding glyph indices.
   *
   *   char_name ::
   *     An array of corresponding glyph names.
