In Perl, the Exporter module is frequently used to manage exporting symbols (functions, variables) from one package to another. When dealing with Unicode and encodings, it's essential to be aware of how these interact with the Exporter, especially since different encodings can lead to unexpected behavior if not handled properly.
Here's a brief overview: Perl's strings can handle binary data, UTF-8, and other encodings, but when you export symbols, it's crucial to ensure that exported values are in the expected encoding format. If the values contain non-ASCII characters, you'll need to ensure that they are correctly encoded to prevent issues during import.
Below is an example of how to use the Exporter along with Unicode encoding in Perl:
package MyExporter;
use strict;
use warnings;
use Exporter 'import';
use utf8;
our @EXPORT = qw(my_function);
sub my_function {
my $str = "こんにちは"; # Japanese for "Hello"
return $str;
}
package main;
use MyExporter;
my $greeting = my_function();
print "$greeting\n"; # Outputs: こんにちは
