Expected behavior
This problem is bound to come up, and every time I commit code, this seems to be a nox bug

[lulivi]

@xiaohuazi123 as a temporary fix, you can change "utf-8" for "latin-1" in line https://github.com/theacodes/nox/blob/master/nox/popen.py#L48

[stsewd]

@xiaohuazi123 does this print latin-1 (or something different to utf-8) in your system?

import sys
print(sys.getdefaultencoding())

If so, we could use that instead of harcoding to utf-8.

https://docs.python.org/3/library/sys.html#sys.getdefaultencoding

[Cielquan]

I have got the same problem at another place. My Github Actions workflow fails because of this issue. The strange thing is that at one repo it works and at another it fails. The nox config differs a bit, but the part where it fails is the same command.

The job runs on all three os (ubuntu, macos, windows) and only windows fails.

Working repo CI example
Broken repo CI example

I also checked some sorts of locale settings in the very job-VMs that is failing and both - the working and broken one - have the same settings - on all there OS:

python function	windows	linux	macos
sys.stdout.encoding	cp1252	None	None
sys.getdefaultencoding	utf-8	ascii	ascii
sys.getfilesystemencoding	utf-8	utf-8	utf-8
locale.getpreferredencoding	cp1252	utf-8	utf-8

The error causing \x95 byte is this dot: • which is used by poetry as a bullet character for each python package it installs.

EDIT1:
I monkeypatched nox.command.popen to use sys.getdefaultencoding() instead of hard coded utf-8 and it did not work for my problem. See here.
Afterwards I remembered my table above and it was clear that it would not change a thing. But for linux and macos it still worked even though the encoding changed from hard coded utf-8 to ascii acording to my table above.

EDIT2:
Next I monkeypatched it to use sys.stdout.encoding and it worked. See here. It shows a placeholder � for the dot • but that also does happen on the above mentioned working CI.

[Cielquan]

According to my findings above and in consideration of the above table I would presume that there are 2 solutions to this problem:

1. use sys.stdout.encoding instead of hard coded "utf-8"
2. use locale.getpreferredencoding instead of hard coded "utf-8"

I think the first one would be the better option? My reasoning is that you ask for the encoding of stdout where your goal is to print to.

EDIT1: Also the docs on locale.getpreferredencoding are not that reassuring that it will always work.

EDIT2: I tested the above table on a local windows machine and got utf8 for sys.stdout.encoding and the rest was the same. And it worked with and without the monkeypatched version.
Later when I'm back home I will issue a PR to fix this.

EDIT3: On the in EDIT2 mentioned windows machine I run the git bash shell as integrated terminal in VSCode. Sometimes the monkeypatched version fails and and the next run it works. Makes no sense to me at current. I will try some stuff.

@stsewd I opened a PR if you want to take a look.
