Wrong header with cURL in PHP with Redmine's REST API - php

Question

I'm currently trying to create an issue in Redmine via the REST API. I export the issues from Redmine in a CSV file. Then, I'm creating an xml file from the CSV, then send it to the API with cURL. I'm setting some options :
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_URL => URL_REDMINE,
CURLOPT_HTTPHEADER => array(
'Content-Type: application/xml; charset=utf-8',
'X-Redmine-API-Key: '.KEY_API),
CURLOPT_BINARYTRANSFER => TRUE,
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $dataXML,
CURLOPT_SAFE_UPLOAD => TRUE,
CURLOPT_ENCODING => "utf-8"
));
curl_exec($curl);
echo json_encode(curl_getinfo($curl));
So, I'm clearly saying that the encoding should be UTF-8. But when I print the informations (with curl_getinfo), here's what I get :
{"url":"[URL I was targeting]",
"content_type":"text\/html; charset=iso-8859-1", [...]}
(I erased some irrelevant informations, but if someone wants it entirely, I can paste it.)
So, it says the content_type is text\/html; charset=iso-8859-1 when I set it as application/xml; charset=utf-8. Is there something I didn't understand with REST API?

Following is simple curl call for php with redmine.
**flie class file in redmine/redmine_curl.php**
<?php # Redmine Api
class class_redmine{
function get_upload_token($filecontent){
global $redmine_url , $redmine_key;
$upload_url = $redmine_url.'uploads.json?key='.$redmine_key;
$request['type'] = 'post';
$request['content_type'] = 'application/octet-stream';
//$filecontent = file_get_contents('test.php');
return $token = $this->curl_redmine($upload_url,$request,$filecontent);
//$token->upload->token;
}
#Issue
function create_issue($post_data){
global $redmine_url , $redmine_key;
$issue_url = $redmine_url.'issues.json?key='.$redmine_key;
$request['type'] = 'post';

return $this->curl_redmine($issue_url,$request,$post_data);
}

//Execute the action to login
$postResult = curl_exec($ch);
//if($postResult == false){ return $info = curl_getinfo($ch);}
$response = json_decode($postResult);
//echo '<pre>'; print_r($response); echo '</pre>';
return $response;
}
