any comments on using a function like that?

function asciiToCase($string,$case) {
 if($GLOBALS['TSFE']->tmpl->setup['config.']['locale_all']) {
  $tmp=$GLOBALS['TSFE']->tmpl->setup['config.']['locale_all'];
  setlocale(LC_CTYPE,'en');
  $caseString=$case=='upper' ? strtoupper($string) : strtolower($string);
  setlocale(LC_CTYPE,$tmp);
 } else
  $caseString=$case=='upper' ? strtoupper($string) : strtolower($string);
 return $caseString;
}

maybe it should also take care of BE.
