Idiom #304 Encode string into UTF-8 bytes

Create the array of bytes data by encoding the string s in UTF-8.

data := []byte(s)

In Go, it is idiomatic that strings are already encoded in UTF-8. So we can grab their raw bytes directly.
import static java.nio.charset.StandardCharsets.UTF_8;
byte data[] = s.getBytes(UTF_8);
using System.Text;
byte[] data = Encoding.UTF8.GetBytes(s);

data := []byte(s)
byte data[] = s.getBytes(UTF_8);
byte[] data = Encoding.UTF8.GetBytes(s);
const data = new TextEncoder().encode(s);
var
  data: pbyte absolute s;
my $text = 'Café';

utf8::encode($text);

my @utf8 = unpack('C*', $text);

my $text = 'Café';

my @utf8 = unpack 'C*', Encode::encode 'UTF-8', $text;



data = s.encode('utf8')
data = s.bytes
let data = s.into_bytes();
