QR scan does not support bytes mode format

[newtonick]

When scanning a QR encoding that is 8 bit byte mode there seems to be a few issues.

The bytes are decoded into a string format (maybe UTF-8) ? I would think it would be better to have different output options, like hex as an example.

Here is an example qr:

Here is what I see in the "Confirm QR Text":

This is the hex contents I think should be displayed (or option to display): cfca8c658bc81962549252bc7ac3ba5b0b01d26bcae89f2b5ecebe263dcb2a36

Also when I do save the QR contents and then hit the QR button on the saved contents to display an encoded QR, I get a QR that does not have the same contents or byte encoding.
