Apple has shown off more emoji characters coming to iOS in the future 11.1 update. The characters are part of Unicode 10, which added 56 new emoji; Apple is revealing over 30 of its new designs today in addition to the handful the company put out on World Emoji Day earlier this year.

Android Oreo already has the equivalent characters, and although the vast majority of Android users aren’t yet running that version of the software, app developers are now able to build in support for new emoji even for people on older Android builds. It’s not clear exactly when Apple plans to release iOS 11.1 or versions of macOS and watchOS containing the new emoji, but they'll be available in the beta version of iOS 11.1 next week.
