Booyah! farang FTW!

Here's my test with a very lightly refactored version of the same script:

use v5.14;
use strict;
use warnings;
use utf8;

use Text::CSV_PP;

binmode STDOUT, ':encoding(UTF-8)';

my $csv = Text::CSV_PP->new({
    sep_char    => '🎬',
    quote_char  => '🎥',
    escape_char => '🎥',
    binary      => 1,
});

my @rows;

my $fh = *DATA;

while (my $row = $csv->getline($fh)) {
    push @rows, $row;
}

$csv->eof() or $csv->error_diag();

for my $row (@rows) {
    $row->[4] =~ s/\n\s*/, /g;

    printf "%-24s %s\n", $row->[0], $row->[4];
}

exit 0;

__DATA__
🎥Film🎥🎬🎥Year🎥🎬🎥Awards🎥🎬🎥Nominations🎥🎬🎥Director🎥

🎥No Country for Old Men🎥🎬2007🎬4🎬8🎬🎥🎥🎥 Joel Coen
🎥🎥 Ethan Coen🎥
🎥The Departed🎥🎬2006🎬4🎬5🎬🎥🎥🎥 Martin Scorsese🎥

This correctly produces:

Film                     Director
12 Years a Slave         🎥 Steve McQueen
Argo                     🎥 Ben Affleck
The Artist               🎥 Michel Hazanavicius
The King's Speech        🎥 Tom Hooper
The Hurt Locker          🎥 Kathryn Bigelow
Slumdog Millionaire      🎥 Danny Boyle
No Country for Old Men   🎥 Joel Coen, 🎥 Ethan Coen
The Departed             🎥 Martin Scorsese

Notice that this version handles the literal newline (\n, CR-LF) in the Coen brothers record, which I change to ',' in the output.

Thank you, farang. I stand corrected:  there is a Unicode-capable CSV parser/generator Perl module on CPAN. And I think you just solved a very long-lived problem for me.
