<p>Unless you're using an ancient version of Perl, <c>\w</c> should match any Unicode word character. According to [mod://perlre] there are over 100,000 characters it matches.</p>
<code>
use 5.010;
use strict;
use warnings;
use utf8::all;
my $string = "the café";
say "GOT: $1" if $string =~ /(\w{4})/;
</code>
<p>Make sure your strings are being interpreted as character strings rather than byte strings though. (See [mod://perlunicode] and [mod://utf8].)</p>
