On-screen-emoji
can't you provide something that makes typing emojis and unusual characters easier across all apps something like on-screen-keyboard the keyboard appears on the screen and you press the buttons and the words appears on the text field simple and easy gnome 3.32 will offer emojis within the on-screen-keyboard but but can't you simplify it to a smaller window which can be moved anywhere and has an icon tray which we can launch it from ( maybe its size should be customizable )
