QKeySequence::toString(...) does not work as expectation

https://doc-snapshots.qt.io/qt6-dev/qkeysequence.html

define a QKeySequnce variable (has tried both QKeySequence::SequenceFormat)

QKeySequence("Ctrl+Q,Q", QKeySequence::PortableText)

QKeySequence("Ctrl+Q,Q", QKeySequence::NativeText)

then call QKeySequence::toString() to print it in console or file

it prints below strings:

Ctrl+垿\uDFFF, Q, Q

expect to be

Ctrl+Q,Q
