Below are the warning and error when i execute command fuck

I had the same issue as well.

• Add an environment variable PYTHONIOENCODING=utf-8
• OR change your $PROFILE from
  Powershell iex "$(thefuck --alias)"
  to
  Powershell $env:PYTHONIOENCODING="utf-8" iex "$(thefuck --alias)"

Thanks, worked like a charm.

That didn't work for me. I've set the environment variable, but no success.

I've even reinstalled thefuck with pip, with the environment variable already set. I was hoping that executing the whole python import thefuck with the correct encoding would solve the issue, but no.

So, waiting for more suggestions.

Btw, fuck executes like this, after no commands at all, or after wrong calls like fick; right calls like ls or Get-ChildItem-Color.

If I execute after git stats, fuck will work like a charm.

I am having the same issue with PYTHONIOENCODING set to utf-8.

I wonder if thefuck reads the stdout so any non-utf-8 chars will break this.

PS: I am running thefuck on Python3.7 on a Chinese Windows system.

Solution:

Add this line to profile:

[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
