I have recently realized that my (up-to-date) copy of Accordance on my (up-to-date) Mac is displaying Greek accents oddly. And by "oddly," I mean real garbage. For example, in place of a rough breathing mark, I see ϙ; in place of a rough breathing plus acute, Ϝ (or ϝ); in place of an acute, a circumflex; there are random spaces between letters in a word, sometimes because an accent appears between after a vowel instead of over it (but; etc. I first noticed this with the LXX, but it occurs as well in NA28-T, the Greek Apostolic Fathers, and other Greek texts.
Does anyone have any suggestions?
