From Fedora Project Wiki

There are various ways to input emoji (emoticons) in applications.

The two main ways are:

  1. using the native GUI toolkit support
  2. using ibus support

Some chat applications also provide their own UI for emoji input.

GNOME

Gtk 3 and 4 generally support Emoji input via Ctrl+Period (Ctrl-.), which brings up an emoji chooser UI.

In almost any application (eg browsers) you can also use ibus Emoji input:

  • To activate ibus Emoji mode:
    • in Fedora 37 and later press Super+Period (Win-.)
    • in Fedora 36 and earlier press Ctrl+Period (Ctrl-.)
  • Then an "e" prompt appears.
  • Either enter a keyword in pre-edit and then space to see candidates
  • or press Space to bring up the Emoji selector.

Note that the ibus emoji input is not available in Live images (see bug).

KDE

Qt supports Emoji input via Super+Period (Win-.).

Qt apps currently have emoji font selection issues:

  • tend to prefer monochrome emoji to color (bug)
  • sometimes fail to render emoji (bug)

LibreOffice

Sometimes monochrome emoji are preferred to colored emoji.

Flatpaks

Emoji input and rendering should generally work fine, with above privisos. Some older (electron) flatpaks may have ibus emoji input issues.
