[BUG] Cyrillic and other characters support in QR code from pkpass files

[000exploit]

Similar issue as in SeineEloquenz/fosswallet#110, I see the same question marks when scanning the generated QR code. I don't know, if it's possible to fix this here because of, perhaps, generic way to generate QR codes. I can send .pkpass file as an example, if it necessary.

Just an example, how it works right now:

I was pretty sure I had to do something with messageEncoding in the pkpass parser, it's even marked as a todo, but I indeed had no file to test with so couldn't be sure. If you could send the affected file that would be great yeah :)

@TheLastProject of course I can, but only by sending it via email. It contains sensetive information, so I can't post it here. Is this acceptable for you? I saw an email in your gh profile, may I send to it?

[TheLastProject]

Yeah sure :)

I do prefer public when possible, especially because then stuff can be added to unit tests, but yeah, with files like these I very much understand :)

Just sent it! Check your inbox.

Can confirm: the value is correctly read, but the barcode itself is generated incorrectly. Seems like this might be a similar issue to #1697 and #1496, but the card ID itself is saved fine so easier to debug this probably :)
