EN Define Symbol Set 10-11
Symbol Map (Array of UI)
The symbol map contains a list of symbol index numbers. This list
identifies symbols for the symbol set. (Refer to Appendix D in the PCL
5 Comparison Guide for a MSL and Unicode symbol indexes.) The
symbol map pairs (maps) a character code to a symbol index number.
The range of character code numbers (paired with symbol index
numbers) is the range from the First Code through the Last Code
fields in the header. The first symbol index number in the Symbol Map
field is mapped to the character code whose value is that of the First
Code field; the second symbol index number is mapped to the “First
Code + 1” character code; the third symbol index number is mapped
to the “First Code + 2,” etc., through the last symbol index number,
which is mapped to the value in the Last Code field. The number of
symbol index characters in the array must match the number of
character codes in the range, First Code through Last Code.
If no printable symbol (symbol index number) is associated with a
given character code (as with codes 128 through 160 of Roman-8),
the corresponding entry in the Symbol Map should be 65535
(FFFF Hex).
