In chat, you said Win32API::File's CreateFileW + OsFHandleOpen didn't work. ("I have used Win32API::File, but it does not support converting the file handle for wide calls to Perl equivalents.") I downvoted for not showing what you tried because it does work.
use strict;
use warnings;
use Encode qw( encode );
use File::stat qw( stat );
use Symbol qw( gensym );
use Win32API::File qw( CreateFileW
OsFHandleOpen
GENERIC_READ
FILE_SHARE_READ
OPEN_EXISTING
);
{
# The file name consists of a black heart (U+2665).
my $fn = encode('UCS-2le', "\x{2665}");
my $handle = CreateFileW(
$fn,
GENERIC_READ,
FILE_SHARE_READ,
[],
OPEN_EXISTING,
0,
[]
)
or die("CreateFile: $^E\n");
my $fh = gensym();
OsFHandleOpen($fh, $handle, "r")
or die("OsFHandleOpen: $!\n");
my $stat = stat($fh);
print("atime: ", scalar(localtime($stat->atime())), "\n");
print("mtime: ", scalar(localtime($stat->mtime())), "\n");
print("ctime: ", scalar(localtime($stat->ctime())), "\n");
}
