See if you have a chartype definition like:
<meta http-equiv=Content-Type content="text/html; charset=UTF-8">
on both or either of the pages. Try adding one if you don't or try using UTF-8 if another charset is specified.

UTF-8 was specified, and wasn't working. It works if I use the following:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
