cannot print encoded URL to console with QString
Message 1 in thread
hi all,
I have some encoded URL that I want to print to console using qDebug. but it
give me junk instead of the actual string. I believe that is because encoded
URL has '%' in it, and '%' is special to QString. so everytime qDebug try to
print '%', it mess up and print junk instead (such as hundreds of space or
some negative number)
e.g.
QString n = "some string";
QUrl::encode( n );
qDebug( n ) // this mess up because of %20 in the encoded n
how do I print it properly???
thanks
ben

AFAIK qDebug cannot print QString objects directly, using qDebug ( n.latin1()
); should work properly (note that latin1() isn't exactly i18n friendly
should this be a concern of yours)

You can pass a QString to qDebug, but the problem is that qDebug interprets
the first parameter as a format string and so you're in trouble when your
string contains %-characters. Just do the following:
qDebug("%s", s.latin1());
Concerning the i18n-friendliness is of lesser concern in qDebug output, at
least in my opinion.
