WebClient.DownloadString result is not match with Browser result 2

The following code:

WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
string Url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
return wc.DownloadString(Url);

code returns:

�Q�T�MP�J�A|�^D����~���C�"�����l� ��;I&3=j=�iG�H9Ȓ�J�^� �j��T�Q=HH�'Qm�������1�hF�4�*�������{�x�\o?

when I visit that URL in any web browser, I get:

12:29:45,A ,3540,3567,3600,3621,3690,3515,140,238204,849582597,1,20140914,122945;;1@2825@3523@3583@1700@1,1@2000@3522@3600@8700@2,1@500@3511@3640@2500@1,;19774,99736,1

is there any way to get right string?

also, I use this online Decoder, but I don't get right answer: Universal Online Decoder

In Linqpad you can run the below code, variation from Webclient. As you can see from the picture, its due to the Gzip compression which browser automatically handles. enter image description here

async void Main()
{
    using (var handler = new HttpClientHandler())
    {
        handler.AutomaticDecompression = DecompressionMethods.GZip;
        using (HttpClient client = new HttpClient(handler))
        {
            var result = await client.GetStringAsync("http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64");
            result.Dump();
        }
    }
}

public class WC : WebClient
{
    protected override WebRequest GetWebRequest(Uri url)
    {
        var request = base.GetWebRequest(url) as HttpWebRequest;
        request.AutomaticDecompression = DecompressionMethods.GZip;

        return request;
    }
}

Usage:

var url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64";
var wc = new WC();
wc.Encoding = Encoding.UTF8;
var result = wc.DownloadString(url);

That's not an encoding problem, i think it relates with compression, gzip in this case. Read Uncompressing gzip response from WebClient. That should fix your problem.
