I'm not sure where JSON got involved in that, but if you can manage to
use CBOR instead, it's just as happy with QByteArray as with QString
(and round-trips them to QByteArray, IIRC). For details, see
qtbase/src/corelib/serialization/qcborstream.h
I've also no idea how well it plays with QSettings; hopefully you know
enough to work it out from the QCbor API ...
