Special Characters In Ajax Response

��������������������winu

Above shows ajax response in Firebug and I wish to remove � from ajax response. But this special character only generates when I set ajax action to Yii application. Otherwise its working perfectly. This is my controller




class AjaxController extends Controller{

public function actionIndex() {

        $this->render('index');

    }

public function actionGetMore() {

       echo 'winu';

    }

}



below shows ajax code in view page(index.php)




<?php

$basePath = Yii::app()->getbaseurl(TRUE);

?>

<script>

var processing;

$(document).ready(function(){


    $(document).scroll(function(){


        if (processing)

            return false;


        if ($(window).scrollTop() >= ($(document).height() - $(window).height())*0.<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/cool.gif' class='bbc_emoticon' alt='8)' />{

            processing = true;

           $.ajax({

            type: "POST",

            url:    '<?php echo $basePath.'/index.php/lead/ajax/GetMore'?>',

            success: function(data){

                },

            error: function(){

                }

        });       

        }

    });

});


</script>
