This is the implicit version of QString being called with a QByteArray as
argument, which, according to the docs, decodes it as UTF-8.

Well, the equivalent to what Qt does is passing 'utf-8' as encoding and
'replace' as error handler:
Like explained in my earlier mail, you'll end up with something like question
marks instead of those correct characters, just like you'd with the Qt solution
Just because a solution doesn't raise an exception (which Qt doesn't do in
general) it doesn't mean it's correct or the right thing to do.
The right thing to do would be passing the correct encoding, but I'm not going
to repeat myself again ;-)
