strange output using topercentencoding()

[raj_iv]

pls check th below code n its strange output...i m not able to figure it out

QString params = QString("q=%1&fields=%2")
.arg(QByteArray("mimeType='application/json'").toPercentEncoding().data())
.arg(QByteArray("items").toPercentEncoding().data( ));

Output:
q=mimeType%3D%27applicationitemsFjson%27&fields=it ems

why items coming just after application...wat happened to '/' percent encoded part. If i remove '/' then output is fine.

And what is so strange here? "/" expands to %2F and thus "%2" gets expanded to the second argument given.
