I'm trying to pass paths that are folder names and that may contain non-ANSI characters to external commands in Windows. I've tried both Win32::GetANSIPathName and Win32::LongPath::shortpathL. The former seems to always return the original path and the latter seems to always return an empty string. What am I doing wrong? Thanks.

use v5.16;
use strict;
use warnings;
use Win32 ();
use Win32::Console ();
use Win32::LongPath qw(shortpathL);

Win32::Console::OutputCP(65001); # Request Windows console command out
+put in UTF-8  
my $top = shift;

foreach my $foldername ( map { chomp $_; $_ } qx(dir /b /a:d "$top") )
+ {
    my $path = "$top\\$foldername";
    test( "GetANSIPathName", $path, Win32::GetANSIPathName("$path") );
    test( "shortpathL", $path, shortpathL($path) );
}

sub test {
    my ($name, $path, $testpath) = @_;
    my @report = qx(robocopy /njh /nfl /ndl /np /l /s "$testpath" "x:\
+\nodir");
    print( qq($name path "$testpath" didn't work for "$path"\n) )
        unless grep(/^ *Bytes/, @report);
}
