How does installing modules (cpanm) interact with Unicode and encodings?

Installing Perl modules using cpanm involves handling Unicode and encodings, which is crucial for ensuring that text data is processed correctly. cpanm, being a command-line tool, must be configured to handle the character sets used in your source code and reliably manage the output.

When you run cpanm, it utilizes the system’s default encoding unless specified otherwise. Therefore, it's essential to understand the interaction between your terminal's encoding and the Perl modules you are installing. This ensures that any Unicode characters in your modules are handled appropriately.

Here’s a brief overview of how to set up your environment to correctly manage Unicode and encodings when using cpanm:

#!/usr/bin/env perl use strict; use warnings; # Use utf8 encoding use utf8; # Set the output to be in UTF-8 binmode(STDOUT, ':utf8'); # Example of a message containing Unicode my $message = "Hello, World! ????"; print "$message\n";
