cout << "▘"

output = "?"

#include <iostream>
#include <Windows.h>
#include <string>

using namespace std;

int main() {
system("CLS");

cout << "▘";

return 0;

}

I think you meant to output the string not to read the character.

Also the code should be inside
```cpp
code in new line
```

int main(){ return 0; }

For unicode instead of using std::cout, you have to use std::wcout and for unicode input you should use std::wcin instead of std::cin.

And for strings std::wstring instead of std::string, and wchat_t[] instead of char[]

#include <iostream>
#include <Windows.h>
#include <string>

int main() {
    system("CLS");

    std::wcout << L"▘";

    return 0;
}

Make sure that the font that your program is using has this code point, otherwise you might get the ? again.

The L before "" means that the text should be encoded in wchar_t rather than char.

I'd use the regular std::cout, but switch it to UTF-8 mode.

#include <iostream>

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#define NOMINMAX 1
#include <windows.h>
#endif

int main()
{
    #ifdef _WIN32
    SetConsoleCP(CP_UTF8);
    SetConsoleOutputCP(CP_UTF8);
    #endif

    std::cout << "▘\n";
}

Make sure your source code is saved as UTF-8 as well

std::print() and std::println() are also probably worth mentioning since they handle utf-8 nicely compared to std::cout.

;compile clang_trunk -std=c++23

#include <cstdint>
#include <print>
#include <string>

static std::string to_utf8_str(uint32_t c) {
    char seq[8]{};

    int32_t n{ 0 };
    if (c < 0x80)
        n = 1;
    else if (c < 0x800)
        n = 2;
    else if (c < 0x10000)
        n = 3;
    else if (c < 0x200000)
        n = 4;
    else if (c < 0x4000000)
        n = 5;
    else if (c <= 0x7fffffff)
        n = 6;

    seq[n] = '\0';

    switch (n) {
        case 6:
            seq[5] = 0x80 | (c & 0x3f);
            c = c >> 6;
            c |= 0x4000000;
            [[fallthrough]];
        case 5:
            seq[4] = 0x80 | (c & 0x3f);
            c = c >> 6;
            c |= 0x200000;
            [[fallthrough]];
        case 4:
            seq[3] = 0x80 | (c & 0x3f);
            c = c >> 6;
            c |= 0x10000;
            [[fallthrough]];
        case 3:
            seq[2] = 0x80 | (c & 0x3f);
            c = c >> 6;
            c |= 0x800;
            [[fallthrough]];
        case 2:
            seq[1] = 0x80 | (c & 0x3f);
            c = c >> 6;
            c |= 0xc0;
            [[fallthrough]];
        case 1:
            seq[0] = static_cast<char>(c);
    }
    return { seq, seq + n };
}

int main() {
    for (uint32_t i = 1024; i < 1279; ++i) {
        std::string asdf = to_utf8_str(i);
        std::print("{}", asdf);
    }
}
