--- Comment #2 from Mike FABIAN mfabian@redhat.com --- Created attachment 1407858 --> https://bugzilla.redhat.com/attachment.cgi?id=1407858&action=edit emoji-picker-flags-gnome-terminal.png
That is a gnome-terminal problem. It works in gedit and in other gnome programs like in the "enter command" dialog as shown in this screenshot.
gnome-terminal cannot display most emoji sequences correctly (i.e. emoji which consist of more than one character). For example, gnome-terminal cannot display any of the following emoji sequences correctly:
🇨🇦 👩🌾 👩❤️👨 🙋🏾♀️ 👧🏾
In emoji-picker, if you right click on an emoji, some information about that emoji is displayed. There you can see whether the emoji is a single character or a sequence. For example for the Canadian flag you will find:
🇨🇦 U+1F1E8 U+1F1E6
