[Boost-users] [date_time] UNICODE and wcout problems

Hi,

in MSVC 8.0 _UNICODE build, after I send a ptime to wcout, I can no 
longer print "international" characters. When I use a temporary 
wostringstream for printing the ptime, everything is OK. Minimal repro 
see below (the "2" at the end is never printed). With some characters 
like the "Å¡" in the example, the output is totally cut off; with others, 
like "á", the codepage is changed, so the characters are displayed 
incorrectly.

Any suggestions?

Thanks,
Filip

// _UNICODE must be defined; the "2" is never printed.
#include <string>
#include <iostream>
#include <sstream>
#include <locale.h>

#include <boost/date_time/posix_time/posix_time.hpp>
using boost::posix_time::ptime;
using boost::date_time::not_a_date_time;

int main() {
  wstring intl=L"\x161";
  wostringstream ss;
  ss << ptime(not_a_date_time);
  wcout << ss.str() << endl;
  wcout << intl << endl;
  wcout << L"1" << endl;
  wcout << ptime(not_a_date_time) << endl;
  wcout << intl << endl;
  wcout << L"2" << endl;
}
