as Robert mentioned we could use a Qt helper based on QTextCodec:
QTextCodec *codec = QTextCodec::codecForName("UTF-8");
const QString text = codec->toUnicode(byteArray.constData(),
if (state.invalidChars > 0)
qDebug() << "Not a valid UTF-8 sequence.";
this converts the string and checks for invalid chars in a single pass.
as the stackoverflow author explains, "invalidChars" is not document
but the Class and field are public.
