A few years after Twitter replaced its gun emoji with a green and orange water gun, it has decided to replace it with a regular gun. Employee X announced his job change last week. The company didn't explain the change, but it appears to be in line with the branding of Elon Musk's social network. Twitter was the first to change its water gun emoji in 2018, following the likes of Google and Facebook. (Apple switched in 2016. Microsoft was short retention.)
Eventually, the Unicode Consortium determined which smiling would first continue the platform leadership, and officially renamed the pistolsmileley as "Waterpistol".
The emoticons share a general designation on different platforms, so they share a general platform determined by the Unicode Consortium (U+1F52B is a pistol pistol). However, each owner of the platform decides how they are visually expressed. This is a method that has won the great defeat of the picture letters CHISBURGER approved in November 2017.
If you look at X on the Internet, the pistol will be displayed. When writing this article, it doesn't seem to be updated on the mobile version of the application, but it is clear.
