Doing work with XML::Atom is possible, but hard due to the poor
documentation. I would suggest:
1. Use the latest version (just in case you're not already).
2. Explicitly passing in "Version => 1.0" whenever you create a new
XML::Atom object. Otherwise you get weird mixed namespaces. Either
that, or Atom 0.3, which is deprecated.

The way to fix this is to serve the RSS feed with a type of
'application/rss+xml' type ('application/atom+xml' for Atom). CGI.pm
will only set the charset if the media type is text/*.
Sending out XML as text/* is frowned upon. This is because proxies are
allowed to recode it into different character sets. Which could break
the XML because they wouldn't know to update the <?xml version="1.0"
charset="iso-8859-9" ?> header as well. So use application/* instead.
