For a C++ console application compiled with Visual Studio 2008 on English Windows (XP,Vista or 7). Is it possible to print out to the console and correctly display UTF-8 encoded Japanese using cout or wcout?

For anyone need to read UTF-8 from file and print to console can try wifstream, even in visual studio debugger shows UTF-8 words correctly (I'm processing traditional chinese), from this post:

#include <sstream>
#include <fstream>
#include <codecvt>

std::wstring readFile(const char* filename)
{
    std::wifstream wif(filename);
    wif.imbue(std::locale(std::locale::empty(), new std::codecvt_utf8<wchar_t>));
    std::wstringstream wss;
    wss << wif.rdbuf();
    return wss.str();
}
 
//  usage
std::wstring wstr2;
wstr2 = readFile("C:\\yourUtf8File.txt");
wcout << wstr2;
