cURL response not readable

Question

I have a problem with my cURL response, when I try to invoke the method of WSDL, I receive this weird text from my browser,

�d�ْ�<�_��[�7�4eS�@���8 �]��Q��A���>�t�,����]�1��%Y���4!l�^ZG��,8��v��������#ZJ�W��

How can I solve this?

Here's my header

$headers = array(
                "Accept-Encoding: gzip, deflate",
                "Content-Type: text/xml;charset=\"UTF-8\"",
                "SOAPAction: \"http://tempuri.org/"",
                "Host: domain.com",
                "Content-length: ".strlen($xml_post_string),
                "Connection: Keep-Alive"
                ); 

and here's my curl options

curl_setopt($soap_do, CURLOPT_URL,            $url);
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($soap_do, CURLOPT_TIMEOUT,        120);
curl_setopt($soap_do, CURLOPT_AUTOREFERER,    true); // new
curl_setopt($soap_do, CURLOPT_MAXREDIRS,      10);   // new
curl_setopt($soap_do, CURLOPT_FOLLOWLOCATION, true); // new
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($soap_do, CURLOPT_POST,           true );            
curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $xml_post_string); 
curl_setopt($soap_do, CURLOPT_VERBOSE,        TRUE); 
curl_setopt($soap_do, CURLOPT_HTTPHEADER,     $headers);

Thank you guys for your comment, I have solve the issue now, shout out to Grokify, I just remove the Accept-Encoding: gzip, deflate and it is now readable.
