Problem with rawurlencode and euro sign.

Hello there, I have a problem with rawurlencode(). I want to have the euro sign € to be sent by post. To do this, first rawurlencode() encodes all the chars. But for some reason rawurlencode encodes it to %3F or %A4. Which i think is logical becouse that is the right position in the charset. But i need it to be %80. When i use rawurldecode('%80'); and put the browsers encoding to ISO-8859-* it does work. i Realy see the euro sign. So why does rawurlencode() not encodes it tho this?. Thx in advance.
