I keep getting question marks in my posts. They turn up mid sentence or at the end of a sentence. A bit annoying actually. I've had to edit most of my posts.
How come? (that one I did type? ☺️)

Not an expert here, but I get those whenever I use an emoji from the emoji keyboard rather than one of the built-in forum ones.

❤️ ? ? Jen is correct about the keyboard emojis.  The heart shows, but a thumb up, and a duck don't.  Let me try some others.  ⭐️???  It doesn't recognize eyes, a birthday cake, and a red tulip.

Ah, ok. Thanks for the explanation.
