using wchar_t in the main function

Question

Is it wrong to use the main function in C++ Visual Studio 2017 as following:

int main(int argc, wchar_t* argv[])

as my program can receive special characters.

Answer 1

Please go and read the remarks section on GetCommandLine:

ANSI console processes written in C can use the argc and argv arguments of the main function to access the command-line arguments. ANSI GUI applications can use the lpCmdLine parameter of the WinMain function to access the command-line string, excluding the program name. The main and WinMain functions cannot return Unicode strings.

Unicode console process written in C can use the wmain() or _tmain() function to access the command-line arguments. Unicode GUI applications must use the GetCommandLineW function to access Unicode strings.

To convert the command line to an argv style array of strings, call the CommandLineToArgvW function.
