Thank you very much for advice, it helped!

If anyone else is interested, here is my working cross-platform code:

#include <QtGui/QApplication>
#include <QtGui/QFileDialog>
#include <QDebug>

#include <iostream>
#include <fstream>
using namespace std;

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QString fileName = QFileDialog::getOpenFileName();
        ifstream ifs;
#ifdef Q_OS_WIN32
    ifs.open(fileName.toStdWString().c_str());
#else
    ifs.open(QFile::encodeName(fileName).data());
#endif
    if (!ifs)
      return 0;

    // Check file contents
    while(ifs) {
        string t;
        ifs >> t;
        cout << t << '\n';
    }
    cout << "OK" << endl;

    return 0;
}
