UTF8 Encoding Issue in Windows

I use Intellij Idea in Windows, with the cp-1252 encoding by default on Windows. I try to execute a python script with the powershell because of problems with subprocess inputs on windows subsystem linux (wsl). The problem is when I try to execute, because powershell pick the encoding by default of windows The content of the ps1 is:

python -c "print('█')"
python generate_dependencies.py

And the content of the python script is:

print("START", file=sys.stdout)
print("█")

And Im getting this weird results:

Is weird because the execution of the python script returns in cp-1252 and the python -c command inline return in weird encoding, I dont know which encoding is.

For me, the issue is that the output is different for run from an OS terminal and for run from the plugin. It should be exactly the same.

I was able to fix it using a hacky workaround:

I'll see how to properly fix it (I assume we should read the terminal encoding used by the IDE instead).
