Describe the bug
when launching the az command there is the following error

Fatal Python error: config_get_locale_encoding: failed to get the locale encoding: nl_langinfo(CODESET) failed
Python runtime state: preinitialized

the error comes from python 3.8 itself cause I have the same error when doing /usr/local/Cellar/azure-cli/2.0.79_2/libexec/bin/python3.8

To Reproduce
brew upgrade azure-cli

Expected behavior
no error on the command

Environment summary
Install Method
brew on catalina 10.15.2

@fengzhou-msft, please help take a look, thanks.

This issue seems to be related with the installation or configuration for python. Can you remove python and azure-cli, then reinstall azure-cli?

thannk for your time, I did that with no luck, and indeed it seems that there is some python issue on my machine, I suspect even something is some native library.
But I don't really know how to solve this.
Is there a way to have az installed in a independent manner without any dependencies ?

I have found the issue, my shell locale was not set up properly.
I had a language set to LANG=en_US instead of LANG=en_US.UTF-8

Thanks for you time, I'll close this issue.
