Slack supports both regular Unicode character entries for emoji, as well as short alpha codes which are converted into an emoji image when posted.

Native emojis are not used on Slack, which defaults to using Apple emoji images and provides user-level preferences to choose from alternatives such as GoogleTwitter or Emoji One.

The setting to change emoji style can be found under the Preferences option inside the Team menu.
