Description:
------------
When an ftp username or password uses the character "#" and when I try to use it in 

curl_setopt($ch, CURLOPT_URL, "ftp://$ftp_user_name:$ftp_pass@$ftp_ip:$ftp_port$path");

cURL will not login with the correct user/pass combination nor the correct IP.


Reproduce code:
---------------
// using ex:  ftp://%e$U^&:!@#$5%@123.145.123.145:456

$ftp_user_name = "%e$U^&" ;
$ftp_pass = "!@#$5%" ;
$ftp_ip = "123.145.123.145";
$ftp_port = 456;
$path = "/";

 $ch = curl_init();

 curl_setopt($ch, CURLOPT_URL, "ftp://$ftp_user_name:$ftp_pass@$ftp_ip:$ftp_port$path");
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 4);  
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_FTPLISTONLY, 0);

 $result['filelist'] = curl_exec($ch); // content
 $result['error'] = curl_error($ch);
 $result['errno'] = curl_errno($ch);



Expected result:
----------------
Loggin in with the correct 
$ftp_user_name = "%e$U^&" ;
$ftp_pass = "!@#$5%" ;
$ftp_ip = "123.145.123.145";
$ftp_port = 456;


Actual result:
--------------
cURL will connect to the IP: #$5%@123.145.123.145 as dysplayed by the error.

As you can see the part before the ip "#$5%" belongs to the ftp_pass, so I think when curl is parsing the url string and encounters "#" (char(35)) it returns the wrong ip.
