Just tell Perl what encoding the file uses. There are several ways:

When opening the file 

open my $OUT, '>:utf8', $filename or die $!;

[download]

Or, after opening the file: 

open my $OUT, '>', $filename or die $!;
binmode $OUT, ':utf8';

[download]

Or, if you want all your output be in UTF-8: 

use open OUT => ':utf8';

[download]

See open, open, binmode for details. You can also use ':encoding(UTF-8)' instead of ':utf8' to let Perl check the validity of the data.
