Using the British pound sign in an XML feed to be read by an iPhone

Question

I have created a web-based UTF-8 XML feed for use in an iPhone application.

When viewing in a web browser, if the feed contains a British Pound sign, I get a nasty X

Answer 1

My final solution which seems to work in all cases is to replace all special chars as they are input.

  public function xmlEntities($text)
  {
    $search = array('&','<','>','"','\'', chr(163), chr(128), chr(165));
    $replace = array('&', '<', '>', '"', ''', '£', '€', '¥');

    $text = str_replace($search, $replace, $text);

    return $text;
  }
