如何用WriteConsoleOutput编写UNICODE或扩展ASCII码

#include <Windows.h>
#include <iostream>
#pragma comment(lib, "user32.lib")

int main()
{
    HANDLE hConsole = CreateConsoleScreenBuffer(GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL);
    COORD bufferSize = {80, 25};
    SetConsoleScreenBufferSize(hConsole, bufferSize);
    SMALL_RECT windowSize = {0, 0, 79, 24};
    SetConsoleWindowInfo(hConsole, TRUE, &windowSize);
    COORD cursorPosition = {0, 0};
    SetConsoleCursorPosition(hConsole, cursorPosition);

    wchar_t unicodeChar = L'\u25A0';
    WORD attributes = FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE;
    DWORD charsWritten;
    WriteConsoleOutputCharacterW(hConsole, &unicodeChar, 1, cursorPosition, &charsWritten);
    WriteConsoleOutputAttribute(hConsole, &attributes, 1, cursorPosition, &charsWritten);

    SetConsoleActiveScreenBuffer(hConsole);

    return 0;
}
