I distinctly remember a time where the emojis we have now didn't work, is that still the case?

On the sCode-page is a link to the emoji cheat sheet, all those codes should work. It only took quite some time for them to show up in signatures last year, but I don't know if that has been fixed yet.

There was a time when Subeta briefly removed emojis, because they were causing the posts to take forever to load for some reason. Fortunately, the new and old emojis don't cause that anymore.

That was what I was referencing, I guess the only way to see if it is would be for me to try. XD;

I remember that. I just didn't know if Subeta reenabled them fully or not.
