Oooops!

We were playing with the fonts earlier, selecting inverted question marks for use in writing Spanish questions. Now it looks like all my apostrophes have turned to question marks in black diamonds. I have gone back and re-edited my post but as it didn't show up on the first post preview, I don't suppose it will this time either, so maybe my editing has had no effect. We'll see. (Plenty of apostrophes in this post just to check for further glitches).
