So do I, but the validator does not. The reason is that the server sends 
quite a different response to it than to "us" (our browsers). This too 
can be seen in the "Show Source" View. Or you could use a utility like 
http://web-sniffer.net/ which takes a URL as input and sends back the 
HTTP headers and the document it gets as response; it naturally does not 
use scripting or cookies, so it probably gets essentially the same 
response as the validator.

No, but here it just does not get it in the response.

(The validator _does_ ignore a <meta> tag specifying charset when the 
charset is specified in an HTTP header, but this is as required by 
specifications and corresponds to browser behavior.)
