When 0 is the leading data in the stream, it is interpreted as a FNC1 as used in
the Code 128 symbology, and specifically for UCC/EAN 128 applications. For
appropriately configured scanners this will be interpreted/transmitted as a ]C1
symbology identifier preamble. The printer does not validate UCC/EAN 128 data
syntax.
When 0 follows a single alphabetic or two numeric characters respectively, then
it also interpreted as a FNC1. For appropriately configured scanners this would be
interpreted/transmitted as a ]C2 symbology identifier preamble, and the alpha or
numeric characters preceding the FNC1 are Application Indicators assigned by AIM
International. The printer does not check AI validity. When 0 is anywhere else in
the data stream, a replaces it in the barcode symbol, as with UCC/EAN 128 field
separators.
Is encoded as FLG(n), and is interpreted as signaling Extended Channel
Interpretation. When the value of n is from 1 to 6, it signals that the following n digits
comprise an extended channel identifier for use with ECI compliant barcode scanners.
An erroneous barcode symbol may result from failing to follow n with n digits.
Any 0 following n and not within the n digits will be encoded as FLG(0). In
the context of a FLG(n), any backslash "\" (9210) will be interpreted by the scanner as
two backslashes "\\".

Behavior
Valid Characters: All ASCII characters, depending upon the selected options.
Variable Length (W1f): This two dimensional barcode holds a large amount of data in
a small area and can provide a high level of error checking.
Specified Length (W1F): With a string four-digit length specifier, values 0x00 through
0xFF to be included within the data strings without conflicting with the DPL format
record terminators.
