How does object construction and new interact with Unicode and encodings?

Understanding how object construction interacts with Unicode and encodings in Perl is crucial for developing applications that handle text data correctly. The 'new' method in Perl is often used for object instantiation, and special attention is required when dealing with Unicode strings and encodings to ensure that your objects handle text data properly.

package MyObject;

use strict;
use warnings;
use utf8; # Enable UTF-8 in the package

sub new {
    my ($class, %args) = @_;
    my $self = {};
    bless $self, $class;

    # Handling a Unicode string
    $self->{text} = $args{text} // ''; 

    return $self;
}

sub get_text {
    my ($self) = @_;
    return $self->{text};
}

# Example of creating an object with Unicode string
my $obj = MyObject->new(text => "Hello, 世界"); # "Hello, World" in Chinese
print $obj->get_text(); # Outputs: Hello, 世界
