Returns a pointer to a UTF-8 string that stays valid at least until the next call to this function. If you need it around any longer, you must copy it. If the key doesn't have a name, this function returns an empty string ("").
See SDL_Scancode and SDL_Keycode for details.
This function is available since SDL 2.0.0.
