Question Strange barcode problem

[kenw232]

We have an Inateck BCST-70 wireless barcode scanner. It works fine. I have changed the settings to stop line feeds/CR after each barcode. This works fine on like thousands of barcodes.

But there is this one barcode that insists on outputting not one but two line feeds after it. This barcode here:

eg.
10809981001108 (enter)
(enter again)

Does anyone know why? How can a barcode have embedded data to make the scanner also output linefeeds when its set not to? What is this called?

I do not KNOW this, but here's my suspicion. A bar code is simply a squence of bars that contain a string of hexadecimal codes for ASCII representations of numbers (usually). But they could contain ASCII codes for other characters, like Line Feed (10 Hex) or Return (13 Hex). I can't "read" bar codes by eye, but those may be in that code you posted.

Yes, I can cut off the last two characters and it fixes it but then all other barcodes break because they're missing two numbers. I can't win.
