python3.10: can't type small letter "b" in REPL

[Nicholas Guriev]

Steps to reproduce:

1. Run in MATE terminal the following command.
    INPUTRC=/dev/null /usr/bin/python3.10
2. Press letter small "b" on the keyboard.

Expected behaviour:

1. "b" is shown on the terminal.
2. The interpreter receives byte representing "b" over stdin.

Actual behaviour:

1. Nothing happens.
2. It is impossible to input this letter.

I was unable to reproduce this problem, I tried in gnome-terminal and mate-terminal, in the cinnamon desktop. My locale is en_US.UTF-8. If this problem persists, it would be helpful to report more details, such as:

the output of usr/bin/locale
the language your keyboard is meant for
whether this is true for other keyboards
whether it is true in other desktops
whether it is true in a plain console, entered through ctrl-alt-F3, etc
