title: ASIHTTPRequest: incorrect NSStringEncoding value 0x0000 detected
body: <blockquote>
    <p>Incorrect NSStringEncoding value 0x0000 detected. Assuming
    NSStringEncodingASCII. Will stop this compatiblity mapping behavior in
    the near future.</p>

  <p>When I was using ASIHTTPRequest, I keep getting this error(50% of the times), what's wrong with it?</p>
  
  <p>I assume the URL I passed in is correct, as it does not contain any space or strange character, maybe it is the result string having some unrecognized character?</p>
