Description

I really don't want emotes like :joy: being converted into Unicode emotes. #50 / #51 solves this in a way, however I do desire Markdown formatting to still work (such as italics, underline, bold text, etc). So the formatChatMessages boolean, as is currently, does not solve my particular use case since it disables all forms of chat formatting, and not just emotes/emojis. (Also I would still like :joy: to show up with yellow text, but that's not a huge deal - I literally just want it to stop converting things into Unicode characters, all other default functionality is fine.)

Why would someone want this? Well I can't speak for others, and other weird scenarios, but my own oddly specific use-case is for compatibility with the Emogg fabric mod.

It sounds good. However, as mentioned in the pinned issue, I don't have time to deal with enhancement issues in this few months. Please be patient or modify the code yourself first, or wait for someone to submit a PR.

I do not really understand. You mean when you type :joy: in-game, :joy: turns to unicode emoji instead of yellow text?
