Create the array of bytes data by encoding the string s in UTF-8.
data = s.bytes
using System.Text;
byte[] data = Encoding.UTF8.GetBytes(s);
data := []byte(s)
const data = new TextEncoder().encode(s);
var data: pbyte absolute s;
use v5.10; use open ':std', ':encoding(UTF-8)'; use utf8;
my $text = 'Café'; utf8::encode($text); my @utf8 = unpack('C*', $text);
use v5.10; use open ':std', ':encoding(UTF-8)'; use utf8; use Encode qw(encode);
my $text = 'Café'; my @utf8 = unpack 'C*', Encode::encode 'UTF-8', $text;
data = s.encode('utf8')
let data = s.into_bytes();
