Datamatrix bytes not decoded correctly in the range from 0x80 to 0xFF #380

I noticed that the app doesn't correctly decode datamatrix codes with bytes in the range from 0x80 to 0xFF. I tested with the version of the app from here and pylibdmtx

Examples: 80 -> C2 80 81 -> C2 81 A0 -> C2 A0 E0 -> C3 A0 F0 -> C3 B0 FF -> C3 BF

It's possible that it's an issue with pylibdmtx, but I've tested with another code sccanner, and it looks to me like it's giving me the expected output

Hm, is it possible to share the DataMatrix code in question?

Unfortunately, I cannot reproduce this.
