What you want to be added?
At this very moment, Discord-Chat-Integration, does not seem to be capable of displaying emojis in minecraft chat. (Looks like this: [][])
Now, there is a mod that adds discords emojis to minecraft, called "Emojicraft".
Emojicraft - on Curseforge
TeamFruit Github

Maybe have DCI utilise Emojicraft, if it's installed?

Version: 1.14.4+

Thank you :)

Mod now has an better implementation. (1.15 only)
Note that you have to import the emotes from that server AND the server requires to have emojicord installed for this to work too
