The problem reported by SB appears to be caused by the wysiyg editor in their admin interface turning certain characters into html entities, and then the rss feeder is escaping those again so that external listeners get a double-escaped entity, producing the problem. My test also showed that copying and pasting from Word into the wysisyg editor by-and-large works, but introduces spurious nbsp entities, so one should use the "paste from word" feature in the editor.
