parse

In supporting barcode symbologies, when the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.

Note: When this option is enabled, literal instances of ^NNN in the input data can be escaped as ^094NNN.

Additionally, control character names can be used to specify equivalent ASCII values, as follows:

Sequence	ASCII value
^NUL	0
^SOH	1
^STX	2
^ETX	3
^EOT	4
^ENQ	5
^ACK	6
^BEL	7
^BS	8
^TAB	9
^LF	10
^VT	11
^FF	12
^CR	13
^DLE	16
^DC1	17
^DC2	18
^DC3	19
^DC4	20
^NAK	21
^SYN	22
^ETB	23
^CAN	24
^EM	25
^SUB	26
^ESC	27
^FS	28
^GS	29
^RS	30
^US	31

Note: ASCII control characters SO and SI cannot be encoded by name (since SO would prefix clash with SOH.

Example

Equivalent symbols:

Data:    This is Data Matrix
Options: 
Encoder: datamatrix

Data:    This is ^068ata Matrix
Options: parse
Encoder: datamatrix

parsefnc

In supporting barcode symbologies, when the parsefnc option is specified, non-data function characters can be specified by escaped combinations such as ^FNC1, ^FNC4, ^SFT/ and ^ECI000003.

Note: When this option is enabled, literal instances of ^ in the input data can be escaped as ^^.

Example

Manually-composed Code 93 Extended demonstrating use of the special shift combination (/)A to represent !:

Data:    TERRY^SFT/A
Options: parsefnc includecheck
Encoder: code93
