Activating venv create unwanted console output

[ShootGan]

Issue
Activating venv shouldn't generate any output. In versions above 20.25.1 it prints () on activation.

20.25.1:

C:\projects\pythontests>venv\Scripts\activate.bat

(venv) C:\projects\pythontests>

20.25.2 (same effect in the latest version)

C:\projects\pythontests>venv\Scripts\activate.bat

C:\projects\pythontests>()

Environment

Provide at least:

• OS: Windows 10, Windows 11
• pip list of the host python where virtualenv is installed:

Package      Version
distlib      0.3.8
filelock     3.14.0
pip          22.0.4
platformdirs 4.2.2
setuptools   58.1.0
virtualenv   20.25.2

Output of the virtual environment creation

Make sure to run the creation with -vvv --with-traceback:
20.25.1

It is caused by this for-loop:

@for /f "tokens=2 delims=:." %%a in ('"%SystemRoot%\System32\chcp.com"') do (
    @set _OLD_CODEPAGE=%%a
)

in this file: src/virtualenv/activation/batch/activate.bat
Adding @echo off fixes this problem but I'm not sure if this is the correct solution.
