C＃通用应用 - condig windows-1250中的RSS

Question

即时通讯带有Feed的通用应用。但是Feed正在编码Windows-1250（http://www.muzikus.cz/save/rss-windows-1250.xml）。唧唧修复显示所有字符？

    public MainPage()
    {
        this.InitializeComponent();
        getFeed("http://www.muzikus.cz/save/rss-windows-1250.xml");

    }

    public async Task<String> getFeed(String feedUrl)
    {
        using (var httpClient = new HttpClient())
        {
            var response = await httpClient.GetAsync(new Uri(feedUrl));
            var xmlString = await response.Content.ReadAsStringAsync();

            var dialog = new MessageDialog("Output: " + xmlString );
            await dialog.ShowAsync();

            return jsonString;
        }
    }
