-   Some HTTP/1.0 software has interpreted a Content-Type header field without
-   charset parameter incorrectly to mean "recipient should guess".
-   Senders wishing to defeat this behavior &MAY; include a charset

-   Unfortunately, some older HTTP/1.0 clients did not deal properly with
-   an explicit charset parameter. HTTP/1.1 recipients &MUST; respect the
-   charset label provided by the sender; and those user agents that have
-   a provision to "guess" a charset &MUST; use the charset from the
-   content-type field if they support that charset, rather than the
-   recipient's preference, when initially displaying a document. See
