How to type Unicode characters in Linux?
Entering Unicode characters in any Linux application is easy if you know the exact, hexadecimal Unicode codepoint number (e.g. U+1F600):
- Press and hold the left Ctrl and Shift keys,
- type U,
- now type in the hexadecimal codepoint sequence: 1, F, 6, 0, 0,
- and finally release Ctrl and Shift.
This method works in GTK- and Qt-applications (all of Gnome and KDE), but also in other popular applications like Google Chrome or Visual Studio Code.
