My database stores some texts which I have to get with AJAX. This is going well but only when it not contains special characters such as ë or ä. I found some articles about this topic which told me to change the charset of the AJAX-request, but none of these worked for me.

When I start firebug it said this about the headers:

Antwoordheaders (dutch for responseheaders)
Cache-Control no-store, no-cache, must-revalidate, post-check=0, pre-check=0

Both of the headers are talking about charset=ISO-8859-15 which should include characters like ë, but it doesn’t work for me.

The code I used for this (PHP): 

`$newresult = mysql_query($query2);    
    $result = array();
    while( $row = mysql_fetch_array($newresult))
    {
        array_push($result, $row);
    }
    $jsonText = json_encode($result);
    echo $jsonText;`

    1. Make sure you set the headers to UTF-8:

      header('Content-Type: application/json; charset=utf-8');

    2. Make sure your connection to database is made with UTF-8 encoding before any queries:

      $query = mysql_query("SET NAMES 'UTF8'");

    3. As far as I know, JSON encodes any characters that cannot be represented in pure ASCII. And you should decode that JSON on response.

    4. Try to move to PDO as mysql_* functions are deprecated. Use this nice tutorial
