Bug Report

Description

Every time I execute dvc list . on my windows 10 (Traditional Chinese), it'll throw ERROR: unexpected error - 'cp950' codec can't decode byte 0xe5 in position 5: illegal multibyte sequence, so I can not list anything.

Reproduce

1. Ensure you have Traditional Chinese version windows 10
2. Install DVC through Windows Installer release or pip install dvc
3. prepare the data
4. execute dvc list .

Expected

a list like:

.dvcignore
.gitignore
.vscode
README.md
data
notebook
requirements.txt
results
results.dvc
utils
var

Environment information

Output of dvc doctor:

$ dvc doctor

If I use local folder as default remote, it works fine. So this problem seems happened only when I use ssh remote. And from Traceback, the error raised on asyncssh package. So this error may due to the under lying ssh package of DVC.

How can I workaround this issue?

It looks like the issue happens when asyncssh tries to parse your OpenSSH configuration file (~/.ssh/config). asyncssh tries to load and parse the file using your terminal's system encoding (cp950), but the SSH config file is probably in utf-8. You may need to set whatever terminal/shell you are using to use utf-8 as the default encoding
