How to Output Unicode Characters to Console in Windows Using C

When attempting to output Unicode characters to the console using std::cout, you may encounter distorted characters instead of the desired Unicode representation. This is because the Windows console by default does not support Unicode output.

To resolve this issue, you need to use the wide-character output stream std::wcout instead of std::cout. std::wcout handles the output of Unicode characters correctly.

#include <iostream>

int main() {
    std::wcout << L"Hello World!" << std::endl;
    return 0;
}

However, it's important to note that the Windows command prompt does not natively support Unicode output. To enable Unicode support, you can use one of the following methods:

• Start cmd with the /u argument.
• Call chcp 65001 to change the output format.
• Set a Unicode font in the console, such as Lucida Console Unicode.

You can also try using _setmode(_fileno(stdout), _O_U16TEXT);, which requires the inclusion of fcntl.h and io.h. By utilizing this approach, you can manually configure the console to handle Unicode output.
