Step file generated from powershell throws error on collection - not UTF-8 encoded

Generate in powershell with: with: pytest-bdd generate features/installer.feature > installer_step_definitions/test_installer_steps.py Run with: pytest

OBS: During test collection error occurs as below. The same file test_installer_steps.py created in VS code and the same code pasted from Notepad++ works.

Note: If I create file by hand and overwrite it by auto generated file this happens:

Original encoding

When I convert to UTF-8 it works fine or if I run in cmd

VS Code encoding is UTF-8

ENV: VS Code Python 3.12

The above exception was the direct cause of the following exception:

I was also able to reproduce this behaviour by generating file again. Notepad++ shows this encoding
