I use primefaces push to write a message in a p:notificationBar. if i push a message with specials characters (like russians char), I've got '?' in my message. How can I fix this problem ? Thanks for your help.

(config : primefaces 3.4 and jsf2. All my html pages are utf8 encoding).

Here is my view code :

<p:notificationBar id="bar"
                widgetVar="pushNotifBar"
                position="bottom"
                style="z-index: 3;border: 8px outset #AB1700;width: 97%;background: none repeat scroll 0 0 #CA837D;">
            <h:form prependId="false">
                <p:commandButton icon="ui-icon-close"
                            title="#{messages['gen.close']}"
                            styleClass="ui-notificationbar-close"
                            type="button"
                            onclick="pushNotifBar.hide();"/>
            </h:form>
            <h:panelGrid columns="1" style="width: 100%; text-align: center;">
                <h:outputText id="pushNotifSummary" value="#{growlBean.summary}" style="font-size:36px;text-align:center;"/>
                <h:outputText id="pushNotifDetail" value="#{growlBean.detail}" style="font-size: 20px; float: left;" />
            </h:panelGrid>
        </p:notificationBar>
        <p:socket onMessage="handleMessage" channel="/notifications"/>

        <script type="text/javascript">
            function handleMessage(data) {
            var substr = data.split(' %% ');
            $('#pushNotifSummary').html(substr[0]);
            $('#pushNotifDetail').html(substr[1]);
            pushNotifBar.show();

            }

        </script>  

and my Bean code :

public void send() { 
        PushContext pushContext = PushContextFactory.getDefault().getPushContext(); 
        String var = summary + " %% " +  detail;
        pushContext.push("/notifications", var);
