Add support for native iOS emojis in engagements

I like to add emojis to engagements to make it more fun for my users. I use the hotkey on mac (command+control+space) to add the emojis. They render perfectly in the editor, but whenever I save the engagement I receive an error message. I see the emoji options you have in the editor, but it’s limited to faces and not other stuff like thumb up, wave, party emojis, etc.
