What is the relationship between GS1 standard barcodes and generic barcode symbols?
We are implementing GS1 linear barcodes (based on Code 128) and GS1 2D barcodes (based on Data Matrix and QR Code) and also GS1 DataBar barcodes in our application.
Since I am new to this, I have few questions regarding GS1-type barcodes:
What is…

Is it possible to decode GS1 Application Identifier formatted data that lacks GS characters to represent FNC1?
I have some data extracted from a GS1 barcode (be it GS1 DataMatrix, GS1 QR Code, GS1 DataBar or GS1-128) that is notionally in GS1 Application Identifier, however the FNC1 separator characters (that are expected to be transmitted as GS characters)…
