      const wchar_t* cat = std::wcschr(arr, L'猫');
      const wchar_t* dog = std::wcschr(arr, L'犬');


      std::cout.imbue(std::locale("en_US.utf8"));


      if(cat)
          std::cout << "The character 猫 found at position " << cat - arr << '\n';
      else
          std::cout << "The character 猫 not found\n";
