Just a cranky comment here: I do know how to do Greek diacriticals. But mudcat has problems with at least some unicode characters -- in particular, ð, þ, and ?. I have had real problems with certain of my posts because of that. So I use HTML entities, because they reliably work on Mudcat -- but there aren't entities for Greek letters with diacriticals.

But, obviously, you folks got it to work. Wish I had a reliable list of just which things Mudcat allows. L-)
