'Avoiding "Setting Locale Failed" Message While Calling Perl

Whenever I run my code: 

$perl my_any_code.pl

It always gives me this:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_CTYPE = "UTF-8",
    LANG = "C"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

How can I avoid that?

Solution 1:[1]

UTF-8 is not a locale name. Set the LC_CTYPE environment variable to a locale that's recognized by your system. It should probably look like en_US.UTF-8. You can get a list of valid locales by running the command locale -a.

Solution 2:[2]

Compile list of your locale definitions and reconfigure it.

locale-gen en_US.UTF-8
dpkg-reconfigure locales

Solution 3:[3]

For me, on Mac M1 Monterey, my quick way to disable that message: Open Terminal -> Preferences -> Advanced tab -> uncheck to Set locale environment variables on startup
