title: As3 urlrequest charset
body: <pre><code>var urlRequest:URLRequest = new URLRequest("子系统.swf");
  loader.load(urlRequest);
  loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
  </code></pre>
  
  <p>Everything works fine when i use native swf to load another swf.
  But after i embed my main swf to html, it reports error:</p>
  
  <pre><code>"NetworkError: 404 Not Found http://127.0.0.1:8020/huanmao/%D7%D3%CF%B5%CD%B3.swf"
  </code></pre>
  
  <p>I don't understand when does "子系统" become "%D7%D3%CF%B5%CD%B3", i can't find any charset option in UrlRequest. If i use English name instead of Chinese, the problem disappeared. 
  This is my html charset setting</p>
  
  <pre><code>http-equiv="Content-Type" content="text/html; charset=utf-8"
  </code></pre>
  
  <p>All my files is edited in utf-8. </p>
  
  <p>I'm really confused. This problem is killing me!
  Any help would be appreciated!!</p>
