Reproducible example

Trying to run pixi shell on Windows 10 with a system path that contains non-ASCII characters produces the following errors:

Running from within a project whose path contains non-ASCII characters produces, in addition, the following errors:

Issue description

Trying to run pixi shell on a Windows 10 system where either the system path or project path contain non-ASCII characters results in errors.

Also see #1362.

Expected behavior

Pixi should activate the environment without error.

Would you happen to have the symbols that you think cause this issue so I can reproduce this locally?

[morags]

Probably any permissible non-ASCII character. Try the following: français, עברית, 日本語.

Side note, this works on linux :+1:
