I would be nice to support alphanumeric Code 128, as brought up by #2. This is also needed for the barcode scanner on the drinks machine at the hackerspace.

Hello,
There is a problem with code-128.
Making a code-128 with only numbers generate a valid barcode that I can read with a device (phone, barcode scaner)
But if you try to generate a code-128 with Letters and numbers the barcode generate can't be read and differt from the real barcade.
Exemple : try to generate the barcode attach in this issue, the result on the flipper is different from the picture
