I don't think you have to give up using Perl.

Something like this should work:

#!/usr/bin/perl

use strict;
use warnings;

use Encode;
use IO::Dir;

# Let perl know that we want to output cp862 on STDOUT
binmode( STDOUT, ':encoding(cp862)' );

my $dir = IO::Dir->new('.')
   or die("Failed to open dir : $!");

while ( my $entry = $dir->read ) {

   next if $entry =~ /^\.{1,2}$/;

   # Decode octets into perl's internal unicode encoding
   $entry = Encode::decode_utf8($entry, 1);

   printf( "%s\n", $entry );
}

$dir->close;
