Description
We encounter problems with a debug build of the qt library on macOS only. When pressing certain keys, an assertion is triggered in QAppleKeyMapper:
Assert: In "qtbase/include/QtCore/../../src/corelib/text/qchar.h", line 114: ASSERT: "rc <= 0xffff" in file qtbase/include/QtCore/../../src/corelib/text/qchar.h, line 114
Along with the following backtrace:

It looks like event->key() returns, e.g., a value of 0x01000000 for the escape key which triggers the assertion:
Qt6/6.1.0/Src/qtbase/src/corelib/text/qchar.h:
> constexpr QCHAR_MAYBE_IMPLICIT QChar(uint rc) noexcept : ucs((Q_ASSERT(rc <= 0xffff), char16_t(rc))) {}
> constexpr QCHAR_MAYBE_IMPLICIT QChar(int rc) noexcept : QChar(uint(rc)) {}
Is this a problem in the debug build of the Qt library or do we need a special flag for our macOS compile?
