What conversion do I need to perform on a file name that contains non-ASCII characters so that I can pass it to MP3::Info::get_mp3info? The code below prints "<file name>: File is empty" for files containing non-ASCII characters (e.g. "Blue Öyster Cult- (Don't Fear) The Reaper".) I want to know how to use the file names produced by console programs, so please no suggestions to rewrite the script so that it uses a completely different method to get the file names. Thanks. Update 4:08PM: I found that converting the file name to a short name with Win32::GetShortPathName and passing the short file name to get_mp3info appears to work correctly, EVEN IF THE SHORT NAME ALSO HAS NON-ASCII CHARACTERS IN IT! (CDBurnerXP generates short names with those characteristics.) There seems to be something about long file names containing non-ASCII characters that makes get_mp3info unable to open the file. 

use strict;
use warnings; 
use Encode;
use MP3::Info;

my $dir = '';

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

for my $rawline (`dir /s $ARGV[0]`)
{
    chop($rawline); # remove newline
    my $line = decode('cp437', $rawline);
    if ($line =~ /^\d/ && substr($line, 24, 1) eq ' ')
    {
        # listing for a file, not a directory
        my $extix     = rindex($line, '.');
        my $filename  = substr($line, 39);
        my $filepath  = "$dir\\$filename";
        my $mp3time   = '';
        if (lc(substr($line, $extix, 3)) eq '.mp')
        {
            # mpeg file
            my $info = get_mp3info($filepath);
            if (defined($info))
            {
                print "$filepath: time is $info->{TIME}\n";
            }
            else 
            {
                print("$filepath: $@\n");
            }
        }
    }
    elsif (substr($line, 0, 14) eq ' Directory of ')
    {
        $dir = substr($line, 14);
        $dir =~ s/\\$//;
        print("$line\n");
    }
}
