[jQuery] jquery and the accents


[jquery-1.1.3.js]
client-side: I have a form with text field and file field. +
iso-8859-1
transmission by ajax to the server
server-side: I have a var_dump($_POST);
First test
I enter in one text field the string "rené" : the dump gives "rené"
Second test
I enter in one text field the string "rené" and in the file field
"logo.gif" : the dump gives "rené"
That means that jquery changes somewhere the charset ? How can I
manage that cleanly ?
