Hello Monks,

I am running strawberry perl 5.30 under windows 11.

I am trying to use fsutil to create an 8dot3 name for a directory name which includes unicode characters. The command is: 

fsutil file setShortName "C:/Users/James/Music/國語&#25079
+;念老歌 Vol. 2" "Vol2~00A"

[download]

FYI, the characters are Chinese - not displayed correctly here for some reason. Anyway, when I enter the command directly into a command shell, it creates the 8dot3 name as desired. But if I try to run the command in a perl program using backticks, it does not work.

Here is my program: 

use strict;
use warnings;

use utf8;
use open ':std', ':encoding(UTF-8)';

use Win32::Unicode;
use Win32::Unicode::Dir;
use Win32::Unicode::File;
use Win32::Unicode::Console;

use Win32::Console;
Win32::Console::OutputCP(65001); # code page for Unicode (UTF-8)

my $cmd = "fsutil file setShortName \"C:/Users/James/Music/國&#3
+5486;懷念老歌 Vol. 2\" \"Vol2~00A\"";

my $trans = `$cmd`;
print "CMD: $cmd\nTRANS: \"$trans\"";

The output is:

CMD: fsutil file setShortName "C:/Users/James/Music/國語&#
+25079;念老歌 Vol. 2" "Vol2~00A"
TRANS: "Error:  The system cannot find the file specified.

Can anyone help me understand why I an getting this result, and what I can change to fix it?

Thanks
