Support for Code 128 Barcodes

[bredowmax]

Summary:
Some products (mostly freshly packaged products with varying weight or price) have Code 128 barcodes that the OFF app does not currently support. The Scandit app does find it

This is a "feature" of the barcodescanner that OFF uses. Or does is this not seen as a valid code? My app does recognizes this code.

[bredowmax]

True, the Edeka example works on my iOS OFF. The WholeFoods one, however, does not get recognised by OFF (Scandit says both codes are a Code 128 code)

[bredowmax]

The Edeka example has 22 digits, but the Whole Foods example has 27 digits

Maybe there is a number of digits check.

Thanks @teolemon for the link. Yes, Code128 is on this list! As @aleene pointed out, Code128 is indeed supported - but apparently they can vary in length. A code with 27 digits was unsupported, so it could be a failed checking number test?

Just checked: Code128 is supported in the IOS app and the Pastrami code is correctly read.

It is also shown in the history.

So for me there is no issue.
