Also if your coding guidelines can use emojis in commit message to mean a certain thing if you all have a common lookup and it becomes natural to see what a change affects. e.g. :bug: for fixing bugs
You can do that with plain ASCII, e.g. Github recognizes the phrase "Closes #123." in commit messages and autocloses that issue when the commit is merged into master. I've seen similar commit hooks in SVN over 10 yrs ago.
