PHP Curl post with non-english characters

Question

I have a small problem with php curl post.

I am trying to post some turkish characters to a forum but aren't posted how it should be.

This is how i save the text:

    fwrite($fpp,"\xEF\xBB\xBF");
    fwrite($fpp, $row['template']);
    fclose($fpp);

and posting:

$this->curl = curl_init();
    curl_setopt ( $this->curl, CURLOPT_URL, $this->vb_url . 'newthread.php?' . $url_vars );
    curl_setopt ( $this->curl, CURLOPT_POST, true );
    curl_setopt ( $this->curl, CURLOPT_POSTFIELDS, $post_fields );
    curl_setopt ( $this->curl, CURLOPT_RETURNTRANSFER, true );
    curl_setopt ( $this->curl, CURLOPT_CONNECTTIMEOUT,20);
    curl_setopt ( $this->curl, CURLOPT_TIMEOUT,10);
    curl_setopt ( $this->curl, CURLOPT_HEADER, true );
    curl_setopt ( $this->curl, CURLOPT_FOLLOWLOCATION, 0);
    curl_setopt ( $this->curl, CURLOPT_COOKIE, $this->cookie_name );
    curl_setopt ( $this->curl, CURLOPT_COOKIEJAR, $this->cookie_name );
    curl_setopt ( $this->curl, CURLOPT_COOKIEFILE, $this->cookie_name );
    curl_setopt ( $this->curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1;    en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1');
   $result = curl_exec ( $this->curl );

this is how it should be:

`Bölüm resimleri, dizi indirme ve altyazı linkine aşağıdan ulaşabilirsiniz.` 

this is how it is posted:

`Bölüm resimleri, dizi indirme ve altyazı linkine aşağıdan ulaşabilirsiniz.` 

Thanks

From http://php.net/manual/es/function.curl-setopt.php

Try adding:

curl_setopt($this->curl,CURLOPT_HTTPHEADER,array (
    "Content-Type: application/x-www-form-urlencoded; charset=utf-8"
));

application/x-www-form-urlencoded suggested by @spencercw
