So it gets a little weirder too because here[1] is an article on their site where they are very clearly using a diacritical character in the main body of the text for "Hernándas" which means whatever backend they're using must support something other than plain ascii. If it was Latin-1 or a similar code page that might explain why they couldn't use the "macron" or "overline" diacritic characters directly, but it doesn't explain why they couldn't just use the HTML escape sequences then, since they can clearly inject them like they did between "Kau Desert" in the Hawaii article.

And while it doesn't say what their backend can do, certainly if you edit in the &#773 escape sequence after the U into the page HTML it seems work, so nothing in the page content itself would make them unable to display the characters. Just makes their note all the more strange.
