Reading UTF-8 characters from console

Question

I\'m trying to read UTF-8 encoded polish characters from console for my c++ application. I\'m sure that console uses this code page (checked in properties). What I have alre

Answer 1

Here is the trick I use for UTF-8 support. The result is multibyte string which could be then used elsewhere:

#include 
#include 
#define MAX_INPUT_LENGTH 255

int main()
{

    SetConsoleOutputCP(CP_UTF8);
    SetConsoleCP(CP_UTF8);

    wchar_t wstr[MAX_INPUT_LENGTH];
    char mb_str[MAX_INPUT_LENGTH * 3 + 1];

    unsigned long read;
    void *con = GetStdHandle(STD_INPUT_HANDLE);

    ReadConsole(con, wstr, MAX_INPUT_LENGTH, &read, NULL);

    int size = WideCharToMultiByte(CP_UTF8, 0, wstr, read, mb_str, sizeof(mb_str), NULL, NULL);
    mb_str[size] = 0;

    std::printf("ENTERED: %s\n", mb_str);

    return 0;
}

Should look like this:
