Why is the command not working in the Ubuntu terminal?

Question

ubuntu

I got a problem in the terminal. When I want to unpack the archive, the console says that I entered the command incorrectly. BUT I ENTERED EXACTLY CORRECTLY.
Here is the part of the error:

[email protected]:/tmp$ tar –xf Python-3.9.5.tgz
tar: invalid option -- '�'
Try 'tar --help' or 'tar --usage' for more information.

Answer 1

It looks like it was copied / pasted, and not entered by hand, the symbol "-" is simply not entered from the keyboard. tar expected "-" (minus), not "-" (dash).
