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?

I'd suspect simply passing hand-entered text through clean() would filter out most or all such things.  And if not, you could always go brute-force and use cleanWith() to enforce a strict whitelist of allowed characters (though you'd have to be fairly careful to be inclusive enough of unusual-but-allowable special characters).

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.

Something like this: https://gist.github.com/aabed/63c4bfde6a510395657a2ee3383716dd
