percent encoding differs in QUrl in Qt4 vs Qt5

[drwho]

Anyone know why the percent encoding differs in QUrl in Qt4 vs Qt5. It appears to be wrong in Qt4....

QUrl url(QString(John's iPho))

actual bytes in QString
4A 6F 68 6E E2 80 99 73 20 69 50 68 6F

The ' is uft = E2 80 99

QUrl in qt4 yields
John%C3%A2%C2%80%C2%99s%20iPho

QUrl in qt5.3.1 yields (correct)
John%E2%80%99s%20iPho

That means there was a bug in Qt 4, and the bug was fixed in Qt 5.

The QString is being formed from a QByteArray. When I make the QString via

QString::fromUtf8(QByteArray)

QUrl in Qt4 correctly percent encodes the QString. I don't think there is a bug in QUrl in Qt4, I guess QUrl in Qt5 is more tolerant.
