- Adds the ability to add emojis using colons 😂 🎉 - The emoji conversion is added to the markdown parser labor - When no emoji is found with the alias, same text is returned - No assets added (no emoji images), so this will only be supported when the browser supports emojis (https://blog.getemoji.com/post/57054354336/which-browsers-support-emoji) - Emoji conversion logic is out of markdown parser labor - Adds its own spec
