			<content:encoded><![CDATA[<p>Gestern hatte ich das Problem, dass json_encode alle Strings mit einem Umlaut einfach gelöscht hatte. utf8_encode brachte auch nichts. Deswegen schnell eine eigene jsonEncode();-Funktion geschrieben! <img src='http://www.punkt16.de/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
<p><span id="more-135"></span></p>
<p>&nbsp;</p>
<p>Diese Funktion ersetzt die json_encode-Funktion komplett. Selbst mehrdimensionale Arrays sind kein Problem, da die Funktion rekursiv programmiert ist.</p>
