Markdown emoji & comment reactions
Stack Overflow comments and answer markdown support Unicode emoji but discourage decorative use. Code blocks and tables use specific markdown — emoji is usually limited to celebratory comments and chat.
How to use: Paste any Unicode emoji directly in a comment. In SO Chat, common `:codes:` work.
