Huh? This is surprising. And what does this program show?

#include <locale.h>
#include <stdio.h>
#include <stdlib.h> 
#include <string.h>

int
main ()
{
  setenv ("LC_ALL", "ar_SA.ISO-8859-1", 1);
  if (setlocale (LC_ALL, "") != NULL)
    {
      printf ("%s\n", setlocale (LC_ALL, NULL));
      printf ("%s\n", setlocale (LC_CTYPE, NULL));
    }
  return 0;
}
