[kronolith] Horde_RPC::request for kronolith: umlaut problem

[roman stachura]

Hi

If i do a Horde_RPC::request in Kronolith things work as expected, till 
i  try to fetch a event titel with umlaut äöü.
The result string will be empty.

Inside Horde the event is displayed correctly.

Its may a charset problem.

Any Suggestion for solving this?

$rpc_endpoint = 'http://your.url.ch/rpc.php';

$rpc_options = array(
           'user' => 'xxx',
           'pass' => 'xxx'
       );
         // XML-RPC method to call
   $rpc_method = 'calendar.listEvents';




$rpc_parameters = array(
                       'startstamp' => $_unix_timestamp_calendar_start,
                       'endstamp' => $_unix_timestamp_calendar_stop,
                       'calendar' => '$_calendar'
               );


// Process the request
$results = Horde_RPC::request(
   'jsonrpc',
   $rpc_endpoint,
   $rpc_method,
   $rpc_parameters,
   $rpc_options
   );
  $results = $results->result;
