The `wcsxfrm` function copies a wide character string into a buffer, such that comparing the new string against any similarly pre-processed string with `wcscmp` produces the same result as if the original strings were compared with `wcscoll`. Our current `wcscoll` implementation is simply an alias for `wcscmp`, so `wcsxfrm` needs to perform no actions other than copying the string.
