Hello, I would like to know how I can create a file that contain special characters in Perl. I have been trying to create a file, with the following function, and it works but it creates an error when it run. I think it is due to the data I am trying to put in my file, for example there are %, @ and others that are to be printed in the file, and I think that the error is due to this. Any ideas on how I can accomplish this? I have attached my code with the error message and one line to be put in the file. Thanks, 

sub CreateConfig{
my ($file,@data) = @_;
$file = $file.".new";
open(NFILE,">$file");
foreach my $item (@data){
printf NFILE "$item\n";
}
close(NFILE);
}
