Regex for uppercase Unicode does not match “Ó”?

Question

It seems that it does not recognize the accented Ó as uppercase

#!/usr/bin/env perl
use strict;
use warnings;
use 5.14.0;
use utf8;
use feature \'unicode_str         


        

Answer 1

You're missing use open ':std', ':locale'; to properly encode your output.

If that doesn't work, your file isn't encoded using UTF-8 even though you tell Perl it is.
