QXmlStreamReader/Writer process the apostrophe char differently.

#include <QXmlStreamReader>
#include <QxmlStreamWriter>
#include <QtDebug>

int main( int argc, char* argv[] )
{
    QApplication a(argc, argv);

    QByteArray byteArray;
    QXmlStreamWriter writer(&byteArray);
    writer.setAutoFormatting(true);
    writer.writeStartDocument();
    writer.writeTextElement("Apostroph", "'");
    writer.writeEndDocument();

    qDebug() << byteArray;

    QXmlStreamReader reader(byteArray);
    while (!reader.atEnd()) {
         if (reader.readNextStartElement())
             qDebug() << reader.readElementText();
     }
    return 0;
}
