Peeking at the text before you decode it doesn't make much sense.

Calling chomp twice makes no sense.

Calling chomp at all doesn't make sense since if you don't add back a newline.

That said, neither of those problems should give you garbage. Maybe the file wasn't in UTF-8? Maybe you're viewer ins't treating the file as UTF-8? Maybe the problem is in how you open IN?

Cleaned up code: 

open(my $fh_in,  '<:encoding(UTF-8)', 'C:\\data.in") or die $!;
open(my $fh_out, '>:encoding(UTF-8)', 'C:\\data.out") or die $!;
while (<$fh_in>) {
    chomp;
    # ...
    print $fh_out "$_\n";
}
