I'm trying to process a feed that contains hex html entities - specifically € for the euro symbol. Zend_Feed is mangling the entities (I get € instead of €). Any suggestions?

Check that your feed encoding is set to UTF-8, and that your server (e.g. Apache) is sending headers to suggest UTF-8 as well.

In Firefox you can right click on the page and select 'View page info' to verify this, or change the encoding in the menu: View->Character Encoding

I don't think it's an character set problem. If I call DOMDocument::save() on the internal DOMDocument in Zend/Feed/Abstract.php that represents the feed, the entities are decoded correctly in the saved file - but then if I do a foreach on the feed items and save them out individually to another file I get the garbled characters.
