How does dispatch tables interact with Unicode and encodings?

Dispatch tables in Perl are a powerful feature that allows for dynamic method selection based on input. When working with Unicode strings and encodings, it is essential to manage character data correctly to prevent issues with incorrect character representation or unexpected behaviors.

Here's a simple example of how a dispatch table can handle different encodings:

#!/usr/bin/perl use strict; use warnings; use utf8; my %dispatch_table = ( 'hello' => sub { print "Hello, World!\n"; }, 'goodbye' => sub { print "Goodbye, World!\n"; }, '¡hola!' => sub { print "¡Hola, Mundo!\n"; }, # Spanish 'こんにちは' => sub { print "こんにちは、世界！\n"; } # Japanese ); my $input = "¡hola!"; # Unicode input if (exists $dispatch_table{$input}) { $dispatch_table{$input}->(); } else { print "Unknown input.\n"; }
