Emojis in Rise

Hello. I recently attended Ginger's webinar on using characters in Rise. At one point we were looking at using the accordion block as a Question/Answer item, and she pointed out how she uses emojis to show correct and incorrect choices. 

I cannot seem to figure out how to insert emojis using the text editor in Rise. Is it an image that is pasted? I unfortunately do not have a visual to share. Or maybe I misunderstood something. 

Thanks!
