Always encodee INI files as utf-8 in Qt6. This is mostly backwards
compatible, as old ini files would encode all non ascii characters.
[ChangeLog][Important behavioral changes] QSettings will now always
encode INI files as utf-8 (and the iniCodec/setIniCode methods are
removed). This is a change from Qt 5 and earlier, where QSettings would
by default escape all non ascii characters. The behavior is equivalent to
what you got in Qt5 by setting a utf-8 iniCodec on the settings object.
Settings files written in Qt 5 will still be readable in Qt 6 (unless
an iniCodec different from utf-8 was used), but to read Qt6 based ini
files in Qt 5 applications, setting the iniCodec to utf-8 is required.

The code did not limit the length of hex and octal escape sequences,
but used an int as the accumulator, which causes UB on overflow.
Due to the use of the QChar(int) constructor when appending escapeVal,
only the lowest 16 bit of the value were appended to the result
string. An test case encoding this behavior explicitly suggests this
is intended behavior.
It therefore suffices to use an unsigned 16-bit value as the
accumulator (unsigned, because that doesn't cause UB on overflow, 16
bits, because that's all we care for).
For future-proofing, use char16_t as the accumulator.
