 * Getting this error after I finished upgrading to “Carmen”. The site still loads
   properly but after applying fix for UTF reading errors I continue to get this
   error listed below.
 * wp-includes/class-json.php on line 115

 * Problems with your backend, eh? 🙂
 * If you’re feeling adventurous, you could try installing 2.9.1 rc1, there was 
   a [bug fixed](http://core.trac.wordpress.org/ticket/11537) in that which might
   solve your problem.
 * You should be able to grab it pretty quickly by following the instructions [here](http://wordpress.org/download/nightly/)(
   the current release is 2.9, despite what that says).

 * Thanks for the fix..two changes to class-json.php and all is well

   > So yes, updating our wrapper to use encodeUnsafe() should do the trick.
