title: PHP header for xml with utf-8
body: <p>I'm using the <strong>header()</strong> function to turn a file into XML standard.
  The problem is when I use <code>&lt;?php header("Content-type: text/xml; charset=utf-8")</code>; ?> it just renders the <code>&lt;?xml version="1.0"?&gt;</code>, without the enconding/charset. Am I using it wrongly?</p>
