Hello!
I would like to prevent users from using emojis in comments, however I have absolutely no idea how to accomplish that. Have you got any advice, folks?

Why do you want to ban them? Because of database issues?
It has been requested, I am not sure why, but I doubt there were any database considerations behind this request.
Blocking a set of specific characters is not simple. To specifically block emojis, you would have to exclude multiple ranges of unicode characters.
