Not sure if this is a bug, or really what to call it, But it looks like the chat output is off, Basically it shows the emoji but right after it shows the text of what the emoji is.
EX: :) in chat outputs

All other emojis do the same.

MC: 1.16.5
Forge: 36.0.46
Emojifull: 1.16.4-2.1.4

Same for me :o

I also have that bug

still an issue on 1.18 with 3.0.1

This happens on servers with changed chat formatting. Instead of "< Player > Message" chat looks like "Player: Message". Since ":" is a special symbol in Emojiful, parsing goes wrong.
Solution is very simple: add a config for specifying the Emojiful symbol. Or at least make one static field char SPECIAL = ':' to make it easier for others to edit.
I myself has replaced ":" with "!" for my server and it works fine.

@Buuz135 This has been present for over a year and a half. Not a single comment on this Github. What's the status of fixing this bug? It essentially renders your mod useless.

Should be fixed in my PR - waiting on a merge and then should be resolved. Sucks that it took this long for it to get fixed but, yeah.

Nice !

Very cool!
