You have to use the encoding "Windows-1252".

header('Content-Encoding: Windows-1252');
header('Content-type: text/csv; charset=Windows-1252');
header("Content-Disposition: attachment; filename={$filename}");

Maybe you have to convert your strings:

private function convertToWindowsCharset($string) {
  $encoding = mb_detect_encoding($string);

  return iconv($encoding, "Windows-1252", $string);
}
