Parsing error, help?

Question

PHP

My code:

set_time_limit(0);
ini_set( 'memory_limit', '256M' );

include $_SERVER['DOCUMENT_ROOT']."/simple_html_dom.php";

function parse($url){
  $uagent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)"; 
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, $uagent);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
  curl_setopt($ch, CURLOPT_COOKIEJAR,$_SERVER['DOCUMENT_ROOT']."/data/cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEFILE,$_SERVER['DOCUMENT_ROOT']."/data/cookie.txt");
  $data = iconv('CP1251', 'UTF-8', curl_exec($ch));
  curl_close($ch);
  return $data;
}

echo str_get_html(parse($url));

Displays above the parser page:

That's it, the question is answered, the drowning man pulled himself out by the hair ))
It turned out that the convenient iconv goes to hell, and CURLOPT_ENCODING comes into play instead)
