C++14: The std::quoted

C++14 allows you to quote strings. Here is an example:

#include <iomanip>
#include <iostream>

int main()
{
  std::cout << std::quoted("To quote: \"Hello.\"  ");
  std::cout <<             "To quote: \"Hello.\"  ";
  std::cout << std::endl;
  return 0;
}
// Output: "To quote: \"Hello.\"  "To quote: "Hello."
