[Tkinter] trace_add question

[DPaul]

emmitted character 00A7 Hex
hyphen is 00AF or 002D Hex (two occ)
You can try codes here: https://barcode.tec-it.com/en/Code128?data=A01-YES
character set used by code 128 is IEC_8859-1

The barcodes generated by the app above are line per line the same
as the ones I generate via the python app in .svg.

It is not the "fault" of the hyphen, because when i try with "#" as separtator,
it also fails. The barcode scanner has very little documentation.
Bus as I said, regex is your friend.
thanks,
Paul
