We can handle the UTF-8 case by reinterpreting it as Latin-1.
This way, the suffixIndex stays valid as a return value.
As a drive-by, optimize away toLatin1() calls by using a QVLA.
We really need a better way of converting UTF-16 -> L1 than
qt_to_latin1()...
[ChangeLog][QtCore][QVersionNumber] fromString() now takes
QAnyStringView (was: QString, QStringView, QLatin1String)
and a qsizetype pointer (was: int pointer).
