Note:
Typically, you will want data compressed unless the data will be decoded with a handheld scanner or your own decode solution that does not include decompression software. For more information about compressing data, see the Acrobat Help.
Specifies the format of the barcode data that is automatically scripted. When an option is selected, the associated script appears in the Script Editor. If required, you can edit the predefined scripts. Select from the following formats:
The value of the barcode is obtained through a script that encodes the data in a delimited format (a flat ASCII representation of field values separated by the specified delimiter character).
Separates the field names using the specified delimiter and encodes them. Field names are listed first, followed by the field values. This option is available when the Delimited option is selected in the Format list.
Uses a legacy encoding format to produce XML barcode content. The legacy encoding format is used in paper forms barcode XML scripts in LiveCycle Designer 7.0 to 8.0. This option is selected automatically when you open a form that uses the legacy encoding format in Designer ES. By default, Designer ES uses a new encoding format.
The paper forms barcode object supports two XML encoding formats produced by two XFA JavaScript functions, xfa.datasets.saveXML() and xfa.record.saveXML(). The legacy encoding format uses the function xfa.datasets.saveXML() and the new encoding format uses the function xfa.record.saveXML()to produce XML encoded data. The legacy encoding format produces longer XML data output than the new encoding format. The new encoding format produces more compact XML data output that provides more barcode space and is better suited for XML encoding scripts.
Specifies the delimiter character that is used to separate field names, field values, and barcode labels in the encoded data. This option is available when the Delimited option is selected in the Format list.
Characters are encoded using Unicode code points as defined by Unicode-3.2, and UTF-8 serialization as defined by ISO/IEC 10646. There is no byte order mark. This option is selected by default.
Characters are encoded using Unicode code points as defined by Unicode-3.2, and UTF-16 serialization as defined by ISO/IEC 10646 and ISO-10646. There is no byte order mark.
Characters are encoded using Unicode code points as defined by Unicode 3.2, and UCS-2 serialization as defined by ISO/IEC 10646. There is no byte order mark.
Note:
Keep in mind that some scanning devices do not support certain character sets. Also, Acrobat and Adobe Reader 7.0. and earlier do not support character encoding.
