cout to wcout

[SwissProgrammer]

// The next line was OK until I used w of std::wcout
std::wcout << "bitset<8>( data[4]).to_string() = [" << bitset<8>(data[4]).to_string() << "] binary\n\n\n";
// error: no match for 'operator<<' (operand types are 'std::basic_ost ream<wchar_t>' and 'std::__cxx11:: basic_string<ch ar>')
