Absolutely.  I'm just quoting the spec to you.  In any case, being able to send
multipart/form-data would be a nice thing to have, if only for file uploads.

Sure.  But nowhere does a spec say that this page charset should be used
in sending the values of a FORM using application/x-www-form-urlencoded
in a new HTTP request.  It's just a convention some browsers use.

Sure, some browsers will.  Others will apparently replace them with
question marks.  It's undefined.
