environment: Windows 10 Pro German/ 1803
cpython @master

When running the venv activate.bat the script fails to reset the codepage to the stored.

# Parameterformat falsch - 65001.

It seems that version 1803 brought a small change to the output of chcp.com - a dot is appended at the output

The issue can be solved by modifying the codepage grep of activate.bat:

A pull will be requested.
