UCC/EAN-128
UCC/EAN-128 is a convention for printing data fields with standard Code 128 bar code
symbols. UCC/EAN-128 symbols are distinguished by a leading FNC 1 character as the first
or second character in the symbol. Other FNC 1 characters are used to delineate fields.
When EAN-128 symbols are read, they are transmitted after special formatting strips off the
leading FNC 1 character, and replaces other FNC 1 characters with the ASCII 29 GS control
character.
When AIM symbology identifiers are transmitted, the modifier character indicates the
position of the leading FNC 1 character according to AIM guidelines. For example, ]c1
indicates a UCC/EAN-128 symbol with a leading FNC1 character.
Standard Code 128 bar codes which do not have a leading FNC 1 may still be used, but are
not encoded according to the EAN-128 convention. Standard Code 128 and UCC/EAN-128
may be mixed in an application. The SE-923 autodiscriminates between these symbols, and
