Hi Horatiu,
bar code symbologies have a default encoding.
Older ones (Data Matrix, QR Code) use ISO/IEC 8859-1 (it is a bit more complicated, as 8859-1 does not define control characters in the range 80-8F).
Newer ones use UTF-8.

Character sets may be changed by ECI, but that is not the only usage of ECIs.

ECI mode simulates the output of a standard scanner:

• no ECI present: Symbology ID flags that, for example ]d1 for Data Matrix
• any ECI present: ECI protocol applies:
  • the symbnology ID flags ECI mode (]d4 for Data Matrix)
  • any present ECI is represented by "\dddddd", where dddddd is the 6 digit ECI number.
  • any data "" is replaced by "\".

I hope this helps, typed to much, soory,
Harald

Hello oehhar,

I apologize for not specifying, but I was referring strictly to QR Codes in this case.

Thank you for the clarification however.

Nicely debugged and thanks for your (first ever) PR! :)
