      Description

      With Qt5, the following code will return 3, but with Qt6 it returns 6:

      QString(QByteArray("foo\0\0\0", 6)).size()

      The documentation of QString(QByteArray) still says this:

      Stops copying at the first 0 character, otherwise copies the entire byte array.

      But it looks like that's not true anymore since QByteArrayView was introduced.

      QString::fromUtf8 and QString::fromLatin1 also do this, but the documentation isn't clear about the correct behavior.
