Arabic in Qt with QString

I want to add an Arabic title to my Qt application, but it didn't work. Here is my code:

#include "mainwindow.h"
#include <QtGui/QApplication>
#include <QString>
#include <QTextStream>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    mainWindow w;
    QString appTitle("تجربه");
    w.setWindowTitle(appTitle);
    w.show();
    return a.exec();
}

And here is the output:

How can I correct it?

Solution

  • That looks like a typical "UTF-8 interpreted as ISO-8859-1" encoding issue. In fact it's a "CP1256 interpreted as Latin1" issue.

    On Windows, with a non-Unicode codepage, try the following:

    QString appTitle = QString::fromLocal8Bit("تجربه");

    If you had your source file in UTF-8, try this instead:

    QString appTitle = QString::fromUtf8("تجربه");

    (See codecForLocale() for what that's supposed to do.)

    Qt Creator 2.7/Windows 7 (in a VM)/UTF-8 source file:
