Character Encoding Syntax: This syntax requires at least two hexadecimal ASCII
digits (0-9, A-F) delimited by the character specified in the <STX>KE command. The
number of hexadecimal digits between the delimiter pair must be even; see notes below.
Syntax:
Where:
•
A delimiter pair with no ASCII hexadecimal pairs between (e.g., \\) will be

interpreted as one byte whose value is that of the delimiting character, allowing the
assigned delimiter to be interpreted as itself rather than as the delimiter.
•
A delimited string that contains either a non-valid hexadecimal character (e.g., FX) or
an odd number of bytes will be treated as an illegal string and, therefore, not
correctly decoded.
Character Encoding Examples: In the following partial datastreams it is assumed that
character encoding is enabled and that the selected delimiter, a backslash (\), has been
transmitted to the printer (i.e., <STX>KEY\). In each example, the printer has not
received an unpaired delimiter prior the example.
Partial Sample Data Stream
AB\\CE
\ABCDEF\
1A\1A\1A
Alternate Control Codes with an Alternate Line Terminator: Character Encoding
can also be used with the Alternate Control Character set. Alternate Control Characters
are enabled, depending upon the model, via a Setup Menu or the <STX>KD / <STX>Kc
commands; see Control Code Command Functions.

Extended System-Level Command Functions
The sample above disables, and then enables character encoding
with the backslash (\) as the delimiter. A UPS MaxiCode will be
formatted using a data string interpreted as follows: [)>
<CR> then formatting is terminated.
