Sorry, I have to throw a little exception there.... the char set for 
URL-encoded get/post data is defined in as the value of 
the form element's accept-charset attribute, which defaults to 
"UNKNOWN", and "User agents may interpret this value as the character 
encoding that was used to transmit the document containing this FORM 
element.".  We rely on this in a system used on hundreds of sites in 
various countries for several years, and we have found no exceptions.

Other that that, I hope our less experienced readers take note of your 
excellent advice.
