How does use utf8 and open layers interact with Unicode and encodings?

In Perl, the 'use utf8' pragma is essential for properly handling Unicode data in your scripts, while the 'open' function, when used with ':encoding(utf8)', helps in reading and writing files with UTF-8 encoding. This combination is crucial for working with multilingual applications and ensures that text is processed correctly. When you work with libraries like OpenLayers that often deal with internationalization, understanding these encodings becomes vital.

This document explains the interaction between 'use utf8' and 'open' in Perl, highlighting their importance in working with Unicode and different encodings, especially when integrating with libraries like OpenLayers.
<?php // Enabling UTF-8 support in Perl use utf8; // Opening a file with UTF-8 encoding open my $fh, '<:encoding(UTF-8)', 'example.txt' or die "Could not open file: $!"; while (my $line = <$fh>) { print $line; } close $fh; ?>
