Wrong decoding with complex datamatrix code #391

eule68 commented 1 year ago

I encountered a wrong decoding with a complex datamatrix code. The code has 96 bytes but was decoded with 97 bytes. One byte were decoded wrong compared to 2 reference scanners. I used Scanbot and a commercial machine vision toolbox (Matrox MIL) as reference with identical readings.

As you can see from the attached files BE decodes the 6th character with C3 followed by a 96 what originally was a D6.

Hm, that looks like a UTF-8 issue 🤔 Thanks for filing an issue! 👍 And sorry for the late reply.

Will investigate…
