 Discovered at http://ilaba.wordpress.com/feed/ -- apparently WordPress
 does not strip out control characters when generating CDATA sections in
 the RSS feed for blogs at wordpress.com. As a result, if an author
 includes a control character (in this case, `^L`) in their post, the CDATA
 section that is wrapped around the post content will be poorly formed.
 Therefore, the XML document for the feed will not be well formed, and
 therefore not parsable by many XML parsers.

 The feed in question was not parsable on scienceseeker.org on 7/6/13,
 which is why I am interested in the question. It may be corrected by its
 owner by the time you test it, so I am attaching a copy of the broken
 version to this ticket.
