Perl warning regarding strange locale setting-CodePudding

I'm currently trying to execute a shell-script in which a perl-exection is also embedded:

$script_dir/gen-cfg.pl \
    --prefix="$outdir" --no-skip-sequences-without-src \
    "${!cfgset/#/${src_cfg_dir}}" \
    "${src_cfg_dir}sequences-cat1.yaml" \
    "${src_cfg_dir}sequences-cat3.yaml" \
    "${extra_args[@]}"

When executing the script I get the following warning:

perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LANG = "ZZ"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

This is all part of generating config files for a C project you can find here. I already know that you can change the used locale in a .bashrc file as described here, but I cannot make sense of the ZZ as a value. I already checked if perl is installed correctly. I'm working on Windows 10 and bash is used for executing perl scripts.

CodePudding user response：

This means that environment variable LANG is set to ZZ, possibly from having done

export LANG=ZZ

Silence the warning by fix this environment variable (e.g. by unsetting it).
