C ++: ASCII printing of hearts and diamonds with an independent platform

Question

I am developing a card game and want to print out the symbol of the heart, diamonds, spades and clubs. My target platform will be Linux.

On Windows, I know how to print these characters. For example, to print a heart (in ASCII), I wrote ...

// in Windows, print a ASCII Heart

#include <iostream>

using std::cout;
using std::endl;

int main()
{
 char foo = '\3';
 cout << heart << endl;
 system ( "PAUSE" );
 return 0;
}

However, as I mentioned, the heart symbol will not be printed on Linux. Is there a standard library that can be used to print a symbol for hearts, diamonds, spades and clubs on Linux and Windows? So far I have been studying Unicode, as I understand that this is universal.

Thanks for any help.

Linux UTF-8 stdout, Unicode .

#include <iostream>

const char heart[] = "\xe2\x99\xa5";

int main() {
    std::cout << heart << '\n';
    return 0;
}

UTF-8 Unicode , fileformat.info ( "UTF-8 (hex)" ).

- . setlocale, . wchar_t char wcout cout.

#include <iostream>
#include <clocale>

const wchar_t heart[] = L"\u2665";

int main() {
    setlocale(LC_ALL, "");
    std::wcout << heart << L'\n';
    return 0;
}

Bottom line: it all depends on the font, and there is no guaranteed portable way to achieve it without bringing your own gylphs.

The top answer is now outdated or incorrect.

ASCII codes for clubs, diamonds, hearts, blades are now '\5', '\4', '\3', '\6'respectively.
