in reply to match utf8

Unless you're using an ancient version of Perl, \w should match any Unicode word character. According to perlre there are over 100,000 characters it matches.

use 5.010;
use strict;
use warnings;
use utf8::all;

my $string = "the café";
say "GOT: $1" if $string =~ /(\w{4})/;

Make sure your strings are being interpreted as character strings rather than byte strings though. (See perlunicode and utf8.)

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

As shown here, locale can also influence the behaviour of `qr/\w/`. Using `qr/\w/u` should also help. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]
