The property HttpWebResponse.CharacterSet returns the wrong charset information. by Oleg Ufaev

If header Content-Type contains "text/" or "text/html" or "text/<something>", and does not contains charset information, then property HttpWebResponse.CharacterSet returns "ISO-8859-1" string.

It occurs because the method HttpWebResponse.CharacterSet contains following code:
...
string text1 = this.m_HttpResponseHeaders.ContentType;
...
string text2 = text1.ToLower(CultureInfo.InvariantCulture);
if (text2.Trim().StartsWith("text/"))
{
    this.m_CharacterSet = "ISO-8859-1";
}
...
while ((num1 = text2.IndexOf("charset", num1)) >= 0)
{
    ...
}

So, if header Content-Type does not contains charset information, "ISO-8859-1" will be returned, by default.

In .NET 1.1, in this case, returned String.Empty.
