[PHP] xmlrpc encoding problem

[Cefull Lo]

Hi,
here's my code
<?php
*$server = xmlrpc_server_create();*
*xmlrpc_server_register_method($server, "showLog", "showLog_func");*
*xmlrpc_server_register_method($server, "showMaxLogId",
"showMaxLogId_func");*
*$request_xml = file_get_contents("php://input");*
*$response = xmlrpc_server_call_method($server, $request_xml, null);*
*print $response;*
*xmlrpc_server_destroy($server);*
?>

All the response given from the server has the header
<?xml version="1.0" encoding="iso-8859-1"?>

Is there anyway to change the encoding to utf-8?

Thanks
