Environment: CentOS 7.6.1810
When logging in from a WSL console (Windows 10, v1809, Build 17763.615 + Ubuntu 18.04) into my CentOS box it seems to be complaining about locale settings.
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "C.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C").
According to this page, you can just add the following lines to /etc/environment file:
LC_ALL="en_US.UTF-8" LC_CTYPE="en_US.UTF-8" LANGUAGE="en_US.UTF-8"
