I use JSON to encode an array, and I get a string like this:

```
{"name":"\u00fe\u00fd\u00f0\u00f6\u00e7"}

```

Now I need to convert this to ISO-8859-9. I tried the following but it fails:

```
header('Content-type: application/json; charset=ISO-8859-9');
$json = json_encode($response);
$json = utf8_decode($json);
$json = mb_convert_encoding($json, "ISO-8859-9", "auto");
echo $json;

```

It doesnt seem to work. What am I missing?

Thank you for your time.
