如何将具有UTF-8文件名的文件复制到Windows上的Perl中的另一个UT

我在它的第一个破解设法访问该文件并创建新的文件名,但副本生成了????,1??.txt.copy.

这是我的第一次破解：

#!/usr/bin/env perl

use strict;
use warnings;

use English '-no_match_vars';
use File::Basename;
use Getopt::Long;

use File::Copy;
use Win32;

my (
    $output_relfilepath,) = process_command_line();

open my $fh,'>',$output_relfilepath or die $!;
binmode $fh,':utf8';
foreach my $short_basename ( glob( '*.txt') ) {

  # skip the output basename if it's in the glob
  if ( $short_basename eq $output_relfilepath ) {
    next;
  }

  my $long_basename = Win32::GetLongPathName( $short_basename );
  my $new_basename  = $long_basename . '.copy';

  print {$fh} sprintf(
                      "short_basename = (%s)n" .
                      " long_basename = (%s)n" .
                      "  new_basename = (%s)n",$short_basename,$long_basename,$new_basename,);
  copy( $short_basename,$new_basename );
}

printf(
       "n%s done! (%d seconds elapsed)n",basename( $0 ),time() - $BASETIME,);

# === subroutines ===

sub process_command_line {

  # default arguments
  my %args
    = (
       output_relfilepath => 'output.txt',);

  GetOptions(
             'help'                 => sub { print usage(); exit },'output_relfilepath=s' => $args{output_relfilepath},);

  return (
          $args{output_relfilepath},);
}

sub usage {
  my $script_name = basename $0;

  my $usage = <<END_USAGE;
======================================================================

Test script to copy files with a UTF-8 filenames to files with
different UTF-8 filenames.  This example tries to make copies of all
.txt files with versions that end in .txt.copy.

  usage: ${script_name} (<options>)

options:

  -output_relfilepath <s>   set the output relative file path to <s>.
                            this file contains the short,long,and
                            new basenames.
                            (default: 'output.txt')

----------------------------------------------------------------------

examples:

  ${script_name}

======================================================================
END_USAGE

  return $usage;
}

以下是执行后output.txt的内容：

short_basename = (BD9A~1.TXT)
 long_basename = (テスト.txt)
  new_basename = (テスト.txt.copy)

我尝试用系统调用替换File::Copy的复制命令：

my $cmd = "copy "${short_basename}" "${new_basename}"";
print `$cmd`;

和Win32 :: CopyFile：

Win32::CopyFile( $short_basename,'true' );

不幸的是,我在两种情况下得到了相同的结果(????,1??.txt.copy).对于系统调用,打印显示1个文件已复制.正如所料.
