Issue saving MSig wallet descriptor to java card #416
Description
Read 2of3 wallet descriptor(QRCode) via Shield Signer running SeSi-0.8.7+ShSi-B12. No problem.
Can save the descriptor onto SEEDKEEPER from SATOCHIP. No problem.
When trying to save the same descriptor onto javacard it fails with:
Error
'utf-8' codec can't decode byte 0xc0 in position 0: Invalid start byte
The javacard was originally prepared via:
DIY tools, Seedkeeper-0.2-official.cap(applet) is installed.

Flashed this version and re-tested with the same 2of3 MSig descriptor. Can confirm that it now is persisted to the card via Seedkeeper functions without any issues. Also can load it back from the card without issues. This is awesome. Thanks
