Hi, Jo - the ’ diphthongs came from those fancy curly apostrophes and quotation marks - the ones that curl in toward the quotation, instead of going straight up and down. When the newest iteration of the 'Cat came online a couple of weeks ago, a lot of fancy characters people had entered were changed to something else. Unfortunately, it's a mistake that's very difficult to correct, so we'll have to live with mistakes in old messages. Those of us with "edit" buttons are correcting the most glaring problems as we see them. I guess we'd be safest using ampersand codes for all those fancy characters, but that gets to be a big task unless you use Teresa's Outlook idea.
The 'Cat still seems to be having problems digesting curled apostrophes. I get error messages when I paste the curly guys into a message.
