cmd does not display the ASCII character 02. It shows a question mark instead. How to fix?

Question

Python

What is the problem? OS Windows 10(x64)

Answer 1

Change the code page to whatever you want.
chcp - Displays the current code page.
chcp 65001 - change to UTF-8.
And in general, something does not add up. I doubt that the ASCII character is not displayed. Any Russian letter is NOT an ASCII character by definition. So tell us more what exactly the symbol is, and how and where you display it, preferably with an example.
