Yes! Amazon Chime 5 and higher supports both emoticons, emojis, and animated gifs in 1:1 and group conversations, chat rooms, and during meetings.
Amazon Chime provides an emoji picker with Unicode emoji on Windows, macOS, and the web app and supports larger display when three or fewer emojis are used, conversion of shorthand emojis [like :) :P etc], skin tone variation, and support for emoji suggestions.

All Amazon Chime clients will auto-complete most face emoticons.
- 8) results in a smiley face with sunglasses
Amazon Chime supports common emoji codes that follow the format :word: (colon word colon)
- :fire: turns into a flame emoji
- :sunny: turns into a sun emoji
To prevent auto-complete, add “/code” to the beginning of the text entry.
- /code 8) does not result in a face with sunglasses.
/code also changes the text to a monospaced font and does not auto-complete URLS.
