You will have to URL-Encode them, these are double byte characters and URL/curl will only get plain ASCII. or if it is a POST request, request data binary.

From the curl Manual:
-d/--data <data>
(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a
browser does when a user has filled in an HTML form and presses the submit button. This will
cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded.
Compare to -F/--form.
-d/--data is the same as --data-ascii. To post data purely binary, you should instead use the --databinary
option. To URL-encode the value of a form field you may use --data-urlencode.
If any of these options is used more than once on the same command line, the data pieces specified
will be merged together with a separating &-symbol. Thus, using ’-d name=daniel -d skill=lousy’
would generate a post chunk that looks like ’name=daniel&skill=lousy’.
If you start the data with the letter @, the rest should be a file name to read the data from, or - if
you want curl to read the data from stdin. The contents of the file must already be URL-encoded.
Multiple files can also be specified. Posting data from a file named ’foobar’ would thus be done
with --data @foobar.
--data-binary <data>
(HTTP) This posts data exactly as specified with no extra processing whatsoever.
If you start the data with the letter @, the rest should be a filename. Data is posted in a similar
manner as --data-ascii does, except that newlines are preserved and conversions are never done.
If this option is used several times, the ones following the first will append data as described in
-d/--data.
--data-urlencode <data>
(HTTP) This posts data, similar to the other --data options with the exception that this performs
URL-encoding. (Added in 7.18.0)

Maybe you'll have to check on the php side for the implementation.
The letter encoding is definitly not what curl did expect.

What is the URL of the web site?  I may be able to show you how to retrieve the letters correctly.  I do not think that the accented characters are double-byte.

CURL retrieves the data correctly, and I find things like Périphériques et Stockage in the text.  

Are you telling the browser that this is UTF-8?  Because Amazon is using this character set:
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />

<?php // RAY_temp_rgb192.php

error_reporting(E_ALL);



// A FUNCTION TO RUN A CURL-GET CLIENT CALL TO A FOREIGN SERVER

function my_curl($url, $timeout=2, $error_report=FALSE)

{

    $curl = curl_init();



    // HEADERS AND OPTIONS APPEAR TO BE A FIREFOX BROWSER REFERRED BY GOOGLE

    $header[] = "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";

    $header[] = "Cache-Control: max-age=0";

    $header[] = "Connection: keep-alive";

    $header[] = "Keep-Alive: 300";

    $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";

    $header[] = "Accept-Language: en-us,en;q=0.5";

    $header[] = "Pragma: "; // BROWSERS USUALLY LEAVE BLANK



    // SET THE CURL OPTIONS - SEE http://php.net/manual/en/function.curl-setopt.php

    curl_setopt( $curl, CURLOPT_URL,            $url  );

    curl_setopt( $curl, CURLOPT_USERAGENT,      'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'  );

    curl_setopt( $curl, CURLOPT_HTTPHEADER,     $header  );

    curl_setopt( $curl, CURLOPT_REFERER,        'http://www.google.com'  );

    curl_setopt( $curl, CURLOPT_ENCODING,       'gzip,deflate'  );

    curl_setopt( $curl, CURLOPT_AUTOREFERER,    TRUE  );

    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE  );

    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE  );

    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout  );



    // RUN THE CURL REQUEST AND GET THE RESULTS

    $htm = curl_exec($curl);



    // ON FAILURE HANDLE ERROR MESSAGE

    if ($htm === FALSE)

    {

        if ($error_report)

        {

            $err = curl_errno($curl);

            $inf = curl_getinfo($curl);

            echo "CURL FAIL: $url TIMEOUT=$timeout, CURL_ERRNO=$err";

            var_dump($inf);

        }

        curl_close($curl);

        return FALSE;

    }



    // ON SUCCESS RETURN XML / HTML STRING

    curl_close($curl);

    return $htm;

}









// USAGE EXAMPLE - PUT YOUR FAVORITE URL HERE

$url = "http://www.amazon.fr/gp/product/B000V9D5LG";

$htm = my_curl($url, 5, TRUE);

if (!$htm) die("NO $url");





// SHOW WHAT WE GOT

echo "<pre>";

$htm = preg_replace('/ +/', ' ', $htm);

$htm = preg_replace('/\n+/', PHP_EOL, $htm);

echo htmlentities($htm);

It's easy enough to try.  I never send the Content-type header - I let my server figure it out for me.
