GS1 Encoding

dBarcode.NET 2D Universal and Datamatrix only

If the Caption string begins with an FNC1 character - ASCII 232 (è) - or the GS1_Flag is on, the Caption is scanned for GS1 Application Identifiers and encoded according to the GS1 Datamatrix specification.

GS1 encoding requires the Application Identifiers to be provided within brackets, eg. (80)12345678(10)123456 so that the AIs can be identified.

Variable length AIs will have FNC1 characters inserted to terminate the AI and all brackets are removed from the encoded data.

During scanning FNC1 characters are replaced by ASCII values of 29.
