Some characters can not be recongized by Python shell in docker

[skyline75489]

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd] 10.0.19041.572
Windows Terminal version (if applicable): master on 67dfbd21a6b37025ebc0cc435c2ddf791e32811a

Any other software?

Docker

Steps to reproduce

Using Python installed by apt install python3 in a ubuntu:18.04 docker image, and Microsoft Chinese IME, type 中文 in Chinese mode in Python shell.

Expected behavior

It works

Actual behavior

Something weird happens:

It feels like I'm using and alt + something.

And I'm using ’ (a Chinese '), sometimes nothing happens. Somethings it feels like I'm typing a ( (and backwards):

It actually works in Python provided by anaconda:

I found some similarity in #7589 , however I'm not sure it's the same thing. I found in convert.cpp, there's CharToKeyEvents which will convert 中文 into alt + 中文, which I do not fully understand.

OK, I've tried this with Guake on Linux. It behaves exactly the same. Now that I think of it, perhaps I should not expect dockered Python without UTF-8 support to naturally accept UTF-8 content.

So, presumably that would mean this is an external bug, yea?
