Yes, for some reason the code manifestation of certain characters has been an issue on the forum. We can't use macrons, circumflexes, acutes, graves, carons, umlauts, or any other sort of diacritic without them turning into their code when we post, although I'm not sure what code it is, exactly. I don't think it's Unicode (UTF-8 or UTF-16). HTML, maybe? Anyway, last I heard thomas said there was some issue with the forum software that made fixing it pretty much impossible, so I've pretty much given up on the idea.
