Is there anyone who knows which emojis you can put in the description of a Scratch project?

You can put any emoji in Scratch project names, Scratch projects, studio names, and the about me section on your profile. So, the short answer is: yes, you can.

They weren't asking if you can, they're asking which ones are supported since not all of them are.

I did not know that, thank you!
