The mod Emojicord adds well emojis to minecraft chat. However the discord chat seems them as their base commands, ie a 😄 in minecraft will appear as :smile : in discord. And the emoji in discord shows up as a square [] in minecraft.

Unless I completely missed something in the config (100% possible) would something like this be possible? Would be really neat.

This feature should already be implemented for 1.14 and 1.15. Won't backport it to 1.12 and, as there is no emojicord for 1.16, i can't port it to 1.16 right now. If you are on 1.15 and it does not work, please comment and I re-open this

I am so sorry, I linked the wrong mod all together. The mod is Emojiful NOT emojicord. My bad. I am on 1.16.3 currently. They are so close name wise..

Oh, great to know there is an up-to-date alternative. Adding to to-do list

I see what is happening here. This also counts as bug, as I was already converting emotes into thier text form ( 😄 -> :smile: ). But it seems that JDA does not count most default emoji as an Emoji object inside of the message. It rather uses unicode symbols which get displayed as [] ingame.

This is what I could produce with an library which tries to convert the unicode emotes back into text, while having emojiful installed on client:

(i was sending random emotes to test)

Going to close this as it now is halfway implemented in the latest 1.16 beta release and I can't really go any step further unless I manually replace every single emote with the text version of it
