c++ - Qt convert unicode entities

Question

In QT 5.4 and C++ I try to decode a string that has unicode entities.

I have this QString:

QString string = "fileu00d6u00c7u015eu0130u011eu00dcu0130u00e7u00f6u015fiu011fu00fcu0131.txt";

I want to convert this string to this: file?????ü????i?ü?.txt

I tried QString's toUtf8 and fromUtf8 methods. Also tried to decode it character by character.

Is there a way to convert it by using Qt?

Answer 1

Qt provides a macro called QStringLiteral for handling string literals correctly.

Here's a full working example:

#include <QString>
#include <QDebug>

int main(void) {
   QString string = QStringLiteral("fileu00d6u00c7u015eu0130u011eu00dcu0130u00e7u00f6u015fiu011fu00fcu0131.txt");
   qDebug() << string;

   return 0;
}

As mentioned in the above comments, you do need to print to a console that supports these characters for this to work.
