Originally created by @SummerGift on GitHub (Aug 12, 2019).

Originally assigned to: @carlos-zamora on GitHub.

Today I updated Windows to 1903 and found that a python program I had written earlier ran incorrectly.

The brief test code is as follows:

import msvcrt
ch1 = msvcrt.getch()
ch2 = msvcrt.getch()
print(ch1)
print(ch2)

When I run the above code in native powershell, press ← key when collecting characters, and it will print b'\xe0' B 'K', and the same code running in the terminal returns b'\x00' b'K'.
This problem didn't appear in the last version of Windows (18.xx).

Steps to Reproduce:

  1. Run this code on the powershell terminal of vscode using Python3
  2. press ← key，record print information
  3. Run this code directly from your powershell on Windows using Python3
  4. press ← key，record print information
  5. Look at different outputs
