I just experimented with a couple of my story summaries, and here’s what I found:
--Periods, commas, question marks, and quotation marks don’t work at all.
--Hyphens work normally.
--Apostrophes now work normally, too. (They used to be replaced by the number 39 for some reason.)
Oddly, this problem only affects some of my stories. There’s no pattern to it that I can see; the problem isn’t confined to a particular story category (it affects some of my stories in Originals and some in Cartoons) or to a particular range of dates (the oldest story of mine that has this problem was posted in 2019).
