G'day Polyglot,

"I think they're called character classes, but please correct me if I've misunderstood"

Both perlrecharclass and perlrebackslash have information on character classes.

Your InThaiHCons() and InThaiLCons() seem overcomplicated. See my example module below.

"The site would not print the UTF-8 characters"

Use <pre> tags for blocks containing characters outside the 7-bit ASCII range. I also use <tt> tags for individual, inline items.

I'm providing you with some sample code which hopefully will get you started.

Here's the module code:

package PolyUniCharClass;

use strict;
use warnings;

{
    my %char_class_despatch = (
        InThaiHCons => \&InThaiHCons,
        InThaiLCons => \&InThaiLCons,
    );

    sub list {
        my ($char_class) = @_;

        unless (exists $char_class_despatch{$char_class}) {
            warn "Char class '$char_class' doesn't exist!\n";
            return [];
        }

        return [
            map chr hex, @{$char_class_despatch{$char_class}->()}
        ];
    }
}

sub InThaiHCons {
    return [qw{0E02 0E03 0E09}];
}

sub InThaiLCons {
    return [qw{0E04 0E07 0E0A}];
}

Here's the script:

#!/usr/bin/env perl

use strict;
use warnings;
use open OUT => qw{:encoding(UTF-8) :std};

use lib '.'; # DEMO ONLY -- DON'T use in PRODUCTION!
use PolyUniCharClass;

print "InThaiHCons:\n";
print @{PolyUniCharClass::list('InThaiHCons')}, "\n";

print "InThaiLCons:\n";
print @{PolyUniCharClass::list('InThaiLCons')}, "\n";

print "InThaiMCons:\n";
print @{PolyUniCharClass::list('InThaiMCons')}, "\n";

Here's a run (note <pre> tags):

ken@titan ~/tmp/pm_11155205_uni_char_class
$ ./uni_char_class.pl
InThaiHCons:
ขฃฉ
InThaiLCons:
คงช
InThaiMCons:
Char class 'InThaiMCons' doesn't exist!
