The Unicode Consortium is the group that organizes and defines new Unicode characters and emoji, and at least once a year, it releases an update that defines which new emoji should be implemented on all platforms. Now, Unicode 15.1 is adding a few more emoji, which should arrive on your PC and mobile devices at some point in the future.
Unicode 15.1 Will Add New Emoji to Your Phone and PC
Expect these to land on an Android 14 or iOS 17 smartphone soon.
