Fabricius

Well, circumflexes only appear on long vowels or diphthongs, so the information a macron gives is already implicitly there. õ or ô works fine in itself. As for the rest, I'm hardly even a beginner student of Greek, so I can't really comment.

I'm not sure how much this counts as a "bug", and it may be nothing at all, but... The Athenian woman unit is named Gýnē Athēnaïkós. I would think that this ought to be Gýnē Athēnaïkḗ, for gender agreement. But, I thought, perhaps Athēnaïkós might be the ending for both masculine and feminine, as with some other adjectives. I wasn't able to find the word on Perseus, however. For the record, my Greek textbook gives Athēnaĩos, Athēnaíā, Athēnaĩon as the standard adjective for Athenian, though I don't doubt that Athēnaïkós is a valid alternative. Am I just tilting at windmills here? I lack the proficiency with Greek to be sure.
