| * @fields: |

| * 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. |
