* @description:
* 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.
