I have slightly modified the program

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
  wstring ws2 = L"Euro:\x20ac";
  wofstream out("unicode.txt");
//  out.imbue(locale("el_GR.UTF-8"));
  out << ws2<< endl;
  wcout << ws2;
}

and this prints the word Euro on the terminal while the
output file is still empty.
