JSON encode für Umlaute funktioniert nicht

Hier ist mein php script:

[code]/*

  • Following code will list all the products
    */

// array for JSON response
$response = array();

// include db connect class
require_once DIR . ‘/db_connect.php’;

// connecting to db
$db = new DB_CONNECT();

// get all products from products table
$result = mysql_query(“SELECT * FROM quotes ORDER BY quotations + 0 DESC”) or die(mysql_error());

// check for empty result
if (mysql_num_rows($result) > 0) {
// looping through all results
// products node
$response[“feed”] = array();

while ($row = mysql_fetch_array($result)) {
    // temp user array
    $feed = array();
    $feed["quotes_id"] = $row["quotes_id"];
    $feed["quote"] = $row["quote"];
    $feed["uid"] = $row["uid"];
    $feed["nameOfCreator"] = $row["nameOfCreator"];
    $feed["imageName"] = $row["imageName"];
    $feed["imageForQuote"] = $row["imageForQuote"];
    $feed["quotations"] = $row["quotations"];
    $feed["created_at"] = strtotime($row["created_at"]);

    // push single product into final response array
    array_push($response["feed"], $feed);
}
// success
$response["success"] = 1;

// echoing JSON response
echo json_encode($response, JSON_UNESCAPED_UNICODE);

} else {
// no products found
$response[“success”] = 0;
$response[“message”] = “No feed found”;

// echo no users JSON
echo json_encode($response);

}[/code]

aber die Ausgabe sieht so aus:

Wie kann ich das “ä” aus der mysql-Datenbank normal ausgeben lassen?
Vielen Dank.

EDIT:
Das Problem habe ich nur bei bplaced. Bei localhost funktioniert das einwandfrei.
