How to use emoji unicode?

Hi, I would like to use emojis as part of my text element by using the emoji unicode code point. I thought this it built in but I can’t seem to get it to show. The plugins I tried didn’t help.
For example where I write U+1F603 (the unicode code point) or 😃 (the HTML entity code) I get what I wrote instead of :smiley:. Is there some markup I need to use?

In contrary to this forum for example where the HTML entity code does work.
