How do you use binmode and encodings with a short example?

In Perl, the `binmode` function is used to set the mode of the filehandle for reading or writing to binary or text. It's particularly useful for setting the encoding of the output like UTF-8.

use strict;
use warnings;
use open ':std', ':utf8';  # Use UTF-8 encoding for standard filehandles

# Open a file for writing
open my $fh, '>:encoding(UTF-8)', 'output.txt' or die "Cannot open file: $!";

# Setting binary mode
binmode($fh, ":utf8");

print $fh "Hello, world!\n";
close $fh;
