now is

$fileName = preg_replace("/\s+|;|\+|=|\[|\]|'|,|\\|\"|\*|<|>|\/|\?|\:|\\$|&|\|/i", "_", $fileName);

what do you think for the italian people?? []

$a = array('/(à|á|â|ã|ä|å|æ)/','/(è|é|ê|ë)/','/(ì|í|î|ï)/','/(ð|ò|ó|ô|õ|ö|ø)/','/(ù|ú|û|ü)/','/ç/','/þ/','/ñ/','/ß/','/(ý|ÿ)/','/(=|\+|\/|\\\|\.|\'|\_|\\n| |\(|\))/','/[^a-z0-9_ -]/s','/-{2,}/s');
$b = array('a','e','i','o','u','c','d','n','s','y','-','','-');
$fileName =  trim(preg_replace($a, $b, strtolower($str)),'-');

a little better

// Cleanup illegal characters
  function cleanUpFileName(&$file) {
    $this->debug("[b]CleanUp FileName[/b]<br/>");
    $fileName = $file->getFileName();
	$desinenza = substr($fileName,strrpos($fileName,"."),strlen($fileName)-strrpos($fileName,"."));
	$nome_file_da_pulire = substr($fileName,0,strlen($fileName)-(strlen($fileName)-strrpos($fileName,".")));

	$a = array('/(à|á|â|ã|ä|å|æ)/','/(è|é|ê|ë)/','/(ì|í|î|ï)/','/(ð|ò|ó|ô|õ|ö|ø)/','/(ù|ú|û|ü)/','/ç/','/þ/','/ñ/','/ß/','/(ý|ÿ)/','/(=|\+|\/|\\\|\.|\'|\_|\\n| |\(|\))/','/[^a-z0-9_ -]/s','/-{2,}/s');
	$b = array('a','e','i','o','u','c','d','n','s','y','-','','-');
	$fileName =  preg_replace($a, $b, strtolower($nome_file_da_pulire)).$desinenza;
    $fileName = substr($fileName, strrpos($fileName, ':'));
    $fileName = preg_replace("/\s+|;|\+|=|\[|\]|'|,|\\|\"|\*|<|>|\/|\?|\:|\\$|&|\||#/i", "_", $fileName);
	if ($this->nameToLower) {
	  $fileName = strtolower($fileName);
	}
    $this->debug("new filename = <font color=\"#000099\">[b]".$fileName."[/b]</font><br/>");
    $file->setFileName($fileName);
  }
