I have this code to get the content of a URL:

        ' Get the HTML response from a server
        ' expC1 Url
        Public Function GetUrl(ByVal tcUrl As String) As String
            Dim lcHTML As String
            Dim loHTTP As System.Net.WebClient = New System.Net.WebClient
            Dim loEncoding As System.Text.Encoding = New System.Text.ASCIIEncoding
            Dim loRequestedHTML() As Byte
            Try
                loRequestedHTML = loHTTP.DownloadData(tcUrl)
                lcHTML = loEncoding.GetString(loRequestedHTML)
            Catch loError As Exception
                lcHTML = loError.Message
            End Try
            Return lcHTML
        End Function

I am wondering about the declaration of the loEncoding. I put ASCIIEncoding for now. But, when getting the content of a URL, is that the proper encoding to use?
