perl - open file in folder with unicode name on Windows -

i have folder on usa windows 7 computer titled "フォルダ". there's file in called "foo.txt", , put few lines of text in it. i'm trying read it, apparently sticky problem. answer related question had simple-looking method open file:

use utf8; use encode::locale; use encode;  $path = 'c:\users\my name\desktop\logrus_workspace\フォルダ\foo.txt'; $new_path = encode(locale_fs => $path); print $new_path; open $fh, '<', $new_path     or die $!; 

the call open dies invalid argument. idea specific problem message indicates, , how can unicode-named file open?

use win32::unicode::native or path::class::unicode.
