I found it. I thought if any web site might be able to handle unicode,
it would be erlang.org, so I went and grabbed some of the header text:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN'
<html xmlns='http://www.w3.org/1999/xhtml'>
  <meta http-equiv='Content-Type' content='text/html;charset=utf-8'/>

and it works correctly now.
