DWR包含一个页面时出现乱码的解决方法

@RemoteMethod
public String getInclude() throws ServletException, IOException {
WebContext wctx = WebContextFactory.get();
//     wctx.getHttpServletRequest().setCharacterEncoding("UTF-8");
wctx.getHttpServletResponse().setCharacterEncoding("UTF-8");
//     wctx.getHttpServletResponse().setContentType("text/html;charset=UTF-8");
return wctx.forwardToString("/forward.html");
}

页面：

function forward() {
Remote.getInclude(function(data) {
dwr.util.setValue("forward", data, { escapeHtml:false });
});
}

<input type="button" value="Include" onclick="forward()">
<div id="forward"></div>
