QFontMetrics::inFont() on Windows returns true even if Qt doesn't find a font that can render the character

Reproducible with the following code, which displays only replacement-characters on Windows:

#include <iostream>
#include <QtGui/QLabel>
#include <QtGui/QApplication>

int main (int argc, char **argv)
{
QApplication app (argc, argv);

QFont f ("Verdana");
// f.setStyleStrategy(QFont::NoFontMerging);
QFontMetrics fm (f);

QString text1;
QString text2;

for (int i = 8305; i < 8317; ++i)

{ bool in_font = fm.inFont (i); text1 += QChar (i); text2 += QString ("\n%1 is in font: %2") .arg (i).arg (in_font? "yes" : "no"); }

QLabel *label = new QLabel;
label->setText (text1 + text2);

label->setFont (f);
label->show ();
return app.exec ();
}

Turning font merging off by commenting in the line shows the correct result from the call to inFont.
