How can I convert HEX encoded Unicode to a QString?

Question

I have a file that contains Strings like:

444541191800B45D01FF00004593244700013030303535202

I think that these are unicode strings. How can i convert them to a Qt QString object? I tried the following:

QByteArray ar1 = inQString.toAscii();
QByteArray ar2 = QByteArray::fromHex(ar1);
QString outQString = QString::fromUtf8(ar2.data());

But his returns a String with only 5 Characters.

I just found the solution myself. The size parameter was missing. Correct Code:

QByteArray ar1 = inQString.toAscii();
QByteArray ar2 = QByteArray::fromHex(ar1);
QString outQString = QString::fromUtf8(ar2.data(), ar2.size());

Or just `fromUtf8(ar2)` (more concise and and ar2.data() creates an unnecessary copy; `.constData()` would avoid that) – Frank Osterfeld Sep 30 '13 at 19:41
Seems not to exist in Qt 4.8 - which i am using. Thanks anyway. – RED SOFT ADAIR Oct 01 '13 at 08:53
