Custom Character Classes
A custom character class (CCC) is a string of up to 50 printable characters that
is associated with a template variable. When a template variable is specified in
a template only characters in the associated CCC string will be allowed in the
specified character position. The variable \G is associated with custom charac-
ter class 1 (CCC1) and the variable \H is associated with custom character
class 2 (CCC2).
CCC strings must specify at least one character for the associated variable to be
used in a template.

code by calculating the total of the data. By default, OCR is configured to use
Modulo 10 check digits. This setting is global to all check digits. The follow-
ing must be true for the placement of a check digit to be considered valid:
