A checksum is mandatory for this barcode (it is always added automatically).
Code 128
Code 128 uses 3 alphabets, each containing 106 characters:
l Alphabet A contains no lower case characters but includes special characters, such as NUL, ACK and FF.
l Alphabet B contains upper and lower case characters.
l Alphabet C is used almost exclusively for double density numeric values, ranging from 00 to 99.
In the case of alphabet A, to enter the non-printable characters listed as ordinals 64 to 94 in the following table, you must use
alphabet B equivalents (for the ACK character, for example, use character f).
The non-printable characters listed as ordinals 95 to 105 can be entered using their ordinal value preceded by ^. To enter
FNC1, for example, you would enter ^102. To enter an actual ^ character, you would enter ^062.
Numeric values entered using alphabet C are always considered as digit pairs (0001, for example, for values 0 and 1). Only
when you use alphabets A or B can you enter an odd number of digits (001, for example, for values 0, 0 and 1).
Having {} taken as a pair of characters to be converted into alphabet C will fail the job and result in a typecheck error.
The following table lists the characters that can be used in all three alphabets:
