Thanks for reply. Um.. to narrow down the err possibility, I've cut and paste the 2 cols into a text file, use notepad, and save as UTF-8. But please tell me if that still not the version that Perl happy with. Here's my code and there are 2 paths see the remarked lines as version 2 : 
use Win32API::File 0.08 qw( :ALL );
#use Win32::Unicode::File;
binmode STDOUT, ":utf8";

open F, "Result_fineName.txt";
#binmode F, ":utf8"; # binmode or not still won't work
my @list = <F>;
close F; chomp @list;

my %hash;
foreach (@list) {
    my ( $id, $name ) = split /\t/, $_, 2;
    $name =~ s/[\\\/\<\>\?\:\|\*]/ /g;
    $name =~ s/ {2,}/ /g;
    $hash{$id} = $name;
}


chdir ( "./doRename/2.4" ) ;
my $source = `dir /b`; 
my @src = split /\n/, $source;
chomp @src;

foreach my $f ( @src ) {
    my @parts = split /[ _]/, $f;
    print $f ;
    MoveFile $f, "$hash{$parts[1]}.mp3" or print  fileLastError() ; #W
+in32API::File
        #moveW $f, "$hash{$parts[1]}.mp3" or print errorW; # Win32::Un
+icode::File

    print $/;    
}

There are 2 sample files in folder 2.4.
One will rename to a file name starts with ANSI char. If I use the Win32API::File way, there is no error raised, it do the rename, but it turns into monster char.
If I use the Win32::Unicode::File way, it raised an err Undefined subroutine Errno::ERROR_FILE_EXISTS called at C:/Perl/site/lib/Unicode/Error.pm line 31.


The other will rename to a pure Japanese file name.
If I use the Win32API::File way, it rasied an err : The filename, directory name, or volume label syntax is incorrect
If use the Win32::Unicode::File way, it does nothing, no err, and no rename.

Note, before I run this from my cmd prompt, I've changed codepage to 65001. Without this, the error message will raise in Chinese ( I guess ), as it showed in monster as well.
