You are.  The Browser will return it in whatever charset was specified 
by the web server feeding it the form, or with the charset specified in 
the attributes of the <form> element, defaulting to ISO-8859-1 if no 
charset was specified.  If you include a character that's not 
representable in the charset selected, it will entity-encode the 
character with &#<unicode value in decimal>;
