How does dual-life modules interact with Unicode and encodings?

Dual-life modules in Perl are modules that can operate in both regular and object-oriented contexts. They often provide interfaces that adapt to both usage patterns, making them flexible and versatile. When it comes to Unicode and character encodings, dual-life modules take on an important role, especially when handling strings in different formats.

The interaction with Unicode and encodings is essential since Perl has robust support for Unicode. Dual-life modules can effectively manage string conversion between different encodings using Perl's built-in functions. This ensures that developers can seamlessly work with text data regardless of its encoding format, allowing for better data handling and manipulation.

Example

use utf8;
use open ":std", ":utf8";

# Using a dual-life module
use Encode qw(encode decode);

my $string = "Hello, Unicode! ????";

# Encode the string to UTF-8
my $encoded = encode("UTF-8", $string);
print $encoded;

# Decode back to a Perl string
my $decoded = decode("UTF-8", $encoded);
print $decoded;
