In practice this isn't one of the big problems. For example, here's an aggregator of a bunch of East Village blogs and news sites. http://east-village.org http://east-village.org The feed titles are the text of the links. You don't see any encoding errors. The blogs use a wide variety of tools to create their feeds. Some are RSS 2.0, some are Atom 1.0. There might even be some of the older formats in there. They always seem to get the titles right. I decode them once. There are generally more problems with descriptions as weird Windows characters pass through their CMSes, and we have to do something with them on our end. Over time my software has gotten pretty good at dealing with these. So when someone raises this "issue" I seem it as more political than pragmatic.
