Hi, you have to tell QString which encoding you are using, like

	QByteArray ba="blabla";
	ba[2]=163;
	ba[3]=168;
	QString textLat1=QString::fromLatin1(ba);
	QString textUTF8=QString::fromUtf8(ba);
	qDebug()<<"Latin1 enconding "<<textLat1<<" utf8 encoding " << textUTF8;

produces

Latin1 enconding  "bl£¨la"  utf8 encoding  "bl��la"

Only QString knows of an encoding, ByteArray is - as the name sugests - a dumb array of bytes with no character meaning.
