Qt attempts to capitalize Germukhi Script. It should not as this script does not distinguish between upper and lower case.

http://en.wikipedia.org/wiki/Mul_Mantar#Translation

This will not be rendered properly:

Text {
font.capitalization: Font.Capitalize
text: "ਡ੍ਰਾਮਾ"
}

The following code prints "Uppercased!"

QString punj = "ਡ੍ਰਾਮਾ";
if(punj.toUpper() == punj) {
qDebug() << "Not Uppercased";
} else {
qDebug() << "Uppercased!";
}
