ASCII Code usage in GNOME

In Windows, I often use combination “Alt + ASCII Code Number” to enter some characters not found on the keyboard. In my Fedora Workstation 42 with GNOME desktop, it doesn’t work or, at least, I don’t know how it works.
In GNOME text editor, nothing happens.
In Terminal and in log-in dialogs, Alt is ignored and the number is printed.
How can I enter a character not found on the keyboard?

To enter a character by its code point, press Ctrl+Shift+U, then type the four-character code and press Space or Enter. If you often use characters that you can’t easily access with other methods, you might find it useful to memorize the code point for those characters so you can enter them quickly.

As I understand it, this should work in GTK apps (so anything “GNOME-native”) - I’m not sure whether it will work on Qt apps in GNOME.

Thank you very much, it works.
Only, this method uses The Unicode Standard, Version 16.0, not ASCII Table of Windows-1252 I’m used to using, so it’s another thing I’ll have to learn to use Linux. OK, let it be :grin:.

For a lot of the characters you can use the compose key, For example
composee gives é and compose " e gives ë.

I the keyboard set-up you can define which key should become the compose key. In a lot of cases this easier than trying to remember the unicode value of these characters.

Thanks.
I misunderstood your advice and typed “compose’ a” in the terminal. Now, I’m stuck with the “>” prompt. I don’t know what it is and I don’t know how to get out of it :woozy_face: . “exit” or “q” don’t work.
Once you stop laughing, dry your tears and explain, please.

First: go into the keyboard set-up and define which key should be the compose key. For example I chose the caps-lock key to be the compose key.

Then to type “^a”

  • hit the compose key
  • hit the ^ key
  • hit the a key

Will it work in log-in dialogs in GNOME?

The log-in dialogs have its own keyboard definition which may or may not be different from the keyboard settings in your normal GNOME session. So, to answer your question: I don’t know, and only testing will tell.

It does not. Too bad, I like to complicate my passwords, that’s why.
Thank you very much for your time and effort. Best regards from sunny Adriatic
