							ENDefine Symbol Set 10-5 The following abbreviations are used to define the data type of each 
field in the symbol set header:
Header Size (UI)
 Set the header size to the size of the header data —  the number 
of bytes from Header Size (byte 0) to the last byte just before the 
beginning of the Symbol Map data bytes. This value is 18 or greater. Font Header Field Data Type Notation
(B)   :  Boolean  (0, 1)
(UB)   :  Unsigned Byte  (0 . . 255)
(SB)   :  Signed Byte  (-128  . .  127)
(UI)   :  Unsigned Integer  (0  . .  65535)
(SI)   :  Signed Integer  (-32768  . .  32767)
(ULI)   :  Unsigned Long Integer  (0  . .  2
32-1)
(SLI)   :  Signed Long Integer  (-2
31  . .  231-1)
(ASCxx)   :  ASCII string  array (0 . . xx-1) of 
characters 
						

							10-6   User-Defined Symbol SetsEN
Encoded Symbol Set Designator (UI)       
This field must match the ID code in the Symbol Set ID code 
command.
This field contains the symbol set ID code. The symbol set ID code is 
calculated from a symbol set ID selection value using the following 
formula:
Symbol Set ID Code = (# * 32) + (ID - 64)
where # is the decimal number (0 to 1023) and ID is the ASCII 
character code of the letter.
For example:
Assume the ID selection value selected for this symbol set is 17Q, 
then:
(17 * 32) + (81 - 64) = 561
The symbol set ID code is 561. 
Format (UB)  
Set this field to 1 for MSL (Intellifont) or 3 for Unicode (TrueType).
Unrecognized values cause the symbol set definition to be ignored. 
Symbol Set Type (UB)
This field defines the printable and unprintable codes for the symbol 
set.
Bit Field  Designated Use
0   7-bit, 32-127 are printable.
1   8-bit, 32-127 and 160-255 are printable.
2   8-bit, 0 - 255 character codes are printable, 
however, to print codes 0, 7-15, and 27, the 
printer must be in transparency mode. 
						

							ENDefine Symbol Set 10-7
First Code (UI)  
Specifies the first character code in the set.
Last Code (UI)  
The Last Code specifies the last character code in the set.
Together, the First Code through the Last Code identify the range of 
character codes which map to the symbol index numbers (characters) 
in the Symbol Map field.
Character Requirements (Array of UB) and 
character requirement   
This 8-byte field works in conjunction with the Character Complement 
field in the header of a type 10 or 11 (unbound) font to determine the 
compatibility of a symbol set with an unbound font. These two fields 
identify the unbound fonts in the printer which contain the symbol 
collections required to build a symbol set. Refer to “Unbound Scalable 
Fonts” in Chapter 9, for a description of symbol collections and 
unbound fonts.
Each bit in the field represents a specific collection. Setting a bit to 1 
indicates that collection is required; setting the bit to 0 indicates that 
collection is not required. (Bit 63 refers to the most significant bit of 
the first byte, and bit 0 refers to the least significant bit of the eight 
byte field.) The bit representations for the collections are shown 
below. (The symbols for each collection are shown in Appendix D 
of the PCL 5 Comparison Guide.)

							ENDefine 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).
