Code 128
Code 128 can encode all the characters currently
encodable in the various code formats presently in
existence. This includes: All ASCII alphanumeric char-
acters (numbers, letters, special characters, control
characters in the 128 character set and the distinction of
the 3 subsets, A, B and C).
Code subset A includes the standard alphanumeric
(upper case only) keyboard characters plus control and
special characters.
Code subset B includes all the standard alphanumeric
keyboard characters and special characters (upper and
lower case).
Code subset C includes a set of 100 digit pairs from 00
to 99 inclusive, allowing definition of double density
numeric digits per symbol, plus special characters.
The last 7 characters in Subsets A and B (96 - 102) and
the last 3 characters in Subset C (100 - 102) are special
characters that are specific to the scanning device.
Code 128 also offers the flexibility to
“shift” to other
subsets in order to combine the
“unique” features into
one condensed bar code.
