HttpClient throws System.ArgumentException: 'windows-1251' is not a supported encoding name

Question

I am writing WinPhone 8.1 app. Code is very simple and works in most cases:

string htmlContent;
using (var client = new HttpClient())
{
    htmlContent = await client.GetStringAsync(GenerateUri());
}
_htmlDocument.LoadHtml(htmlContent);

But sometimes exception is thrown at

htmlContent = await client.GetStringAsync(GenerateUri());

InnerException {System.ArgumentException: 'windows-1251' is not a supported encoding name. Parameter name: name at System.Globalization.EncodingTable.internalGetCodePageFromName(String name) at System.Globalization.EncodingTable.GetCodePageFromName(String name)
at System.Net.Http.HttpContent.<>c__DisplayClass1.b__0(Task task)} System.Exception {System.ArgumentException}

Does HttpClient support 1251 encoding? And if it doesn't, how can I avoid this problem? Or is it target page problem? Or am I wrong in something?

Get response as IBuffer and then convert using .NET encoding classes:

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(uri);
IBuffer buffer = await response.Content.ReadAsBufferAsync();
byte[] bytes = buffer.ToArray();

Encoding encoding = Encoding.GetEncoding("windows-1251");
string responseString = encoding.GetString(bytes, 0, bytes.Length);
