I get files in Windows 7 that have wide chars. I need to rename them after stripping the non-ascii characters from them. Opendir and then readdir (in a while clause) does not work because readdir does bytes!

Below is code that I also tried.


# File name = a1.pl
# Script to get rid of wide chars and non-ascii chars
# in a Windows 7 file name.
# This does not work.
# In the Windows 7 file explorer, the file name shows as
#             "z ‎ay‎  ‎Pow‎.mp4"
# Note: There is at least one embedded wide char in the above
#       pasted file name.
#       The Windows 7 command promt shows the file name
#       as
#             "z ?ay?  ?Pow?.mp4".

use 5.14.2;

# From: how to read unicode filename
# http://www.perlmonks.org/?node_id=536223
open fList, '-|:encoding(UTF-16LE)', 'cmd /U /C dir /W';

# Note: I tried to opendir and readdir.  I got the shortened
#        8.3 character file name whenever a wide character
#        was in the file name.  I could not rename.

foreach (<fList>) {
    utf8::encode($_);
    my $orig_name = $_;
    my $new_name = $_;
    if ($new_name =~ m/.mp4/i) {
    print " 1 orig_name is \"$orig_name\"\n";

    $new_name =~ s![^[:ascii:]]!!ig;
        print " 2 new name  is \"$new_name\"\n";
    rename "$orig_name", "$new_name"; # Does not work
    }
    
}

__END__
In the results below, note that the end double quotes are not
at the end of the file name line!  That should not be!

>a1.pl
 1 orig_name is "z &#915;ÇÄay&#915;ÇÄ  &#915;ÇÄPow&#915;ÇÄ.mp4
"
 2 new name  is "z ay  Pow.mp4
"
