Thanks for the reply.
My understanding is that the barcode string our example is UTF-8 encoded. See, for example the “Encodings” section in the following webpage for the Unicode character 0x0153 (the barcode STOP character):
The UTF-8 (hex) representation of this character is “0xC5 0x93 (c593)” which is exactly what can be found in our example file at the end of the barcode string.
Am I misunderstanding or overlooking something?
