我在angular2应用程序的HTML页面中显示德语变音字符时遇到问题。我的后端服务是在java中，它返回json String。

This is the response of the post request which is shown in network tab. and it shows ü character properly .

这是发布请求的响应，显示在网络选项卡中。它正确地显示了ü字符。

but if i console the data from below snippet, it shows � both in HTML ui and console .

但是，如果我从下面的代码段控制数据，它会在HTML ui和console中显示 。

    getStackById(project: string, stackId: string, ibsessionid: string) {
    var headers = new Headers();
    headers.append('Content-Type', 'application/x-www-form-urlencoded');
    return this.http.post('http://' + this.ip + ':' + this.port + '/IBPublicationBuilder/MiddlewareServlet', 'project=' + project + '&stackid=' + stackId + '&ibsessionid=' + ibsessionid + '&method=getStackById', {
      withCredentials: true, headers: headers
    }).map(
      (res: Response) => {
         console.log(res);
        return res.json()}
      );
