Prototype has _nothing_ to do with the response code.
Your backend is sending the wrong encoding. Problably, you have not
set the correct send headers.
Are you using a PHP backend? If yes, maybe your local php.ini have
default_charset set to utf-8 and the unix one has not, by default, php
uses iso-8859-1.
Try adding this line to you response:
header('content-type:text/plain; charset=utf-8'); // of course, the
content-type you are expecting
or use [1]utf8_encode(CONTENT) before send the response.
