Visual Studio 2019 C에서 CMD 명령에 발트 문자를 사용하는 방법은 무엇입니까?

<code class="cpp">#include <iostream>
#include <locale>

int main()
{
    std::locale::global(std::locale("en_US.UTF-8"));
    std::cout << "ĀāĀā" << std::endl;
}

<code class="cpp">#include <string>
#include <sstream>
#include <iomanip>

std::string toHexString(const std::string& str)
{
    std::stringstream ss;
    for (char c : str)
    {
        ss << std::hex << std::setw(2) << std::setfill('0') << (int)static_cast<unsigned char>(c);
    }
    return ss.str();
}</code>

<code class="cpp">#include <windows.h>
#include <iostream>
#include <string>

int main()
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    ZeroMemory(&pi, sizeof(pi));

    std::string cmd = "cmd /c echo ";
    cmd += "ĀāĀā";

    if (!CreateProcess(NULL, (LPSTR)cmd.c_str(), NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &si, &pi)) 
    {
        std::cerr << "Error executing command" << std::endl;
        return 1;
    }

    WaitForSingleObject(pi.hProcess, INFINITE);

    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);

    return 0;
}</code>
