Pipe symbol (Alt + Shift + L) and tilde symbol (Alt + n ) don't work anymore.

Hello everyone,

Lately pipe symbol (Alt+Shift+L) and tilde symbol (Alt +n) can't be typed in my macbookpro Terminal.

For an unknown reason, it seems to affect only the Terminal behaviour since it's working in TextEdit. At the moment I copy paste both of them from a separate text file, but it can't be a permanent solution.

Does someone have a clue?

(I have a macbook pro early 2015, Catalina 10.15.7 and an azerty keybord).

Thank you very much for your help.
