Facebook had a unique emoji set that previously displayed within Messenger for iOS, Android and web. These emojis were different to those used on the Facebook Desktop Website from June 2016 — September 2017.

As of October 2017 this emoji set has been discontinued. Messenger for iOS now uses native Apple emojis, and Messenger for Android and web uses the Facebook emoji set. See also: 🌙 Crescent Moon for Messenger Dark Mode.
