OCaml friends: How many characters does this print? (It's valid UTF-8 and valid Unicode)

print_endline "\xF0\x9F\x90\x95\xE2\x80\x8D\xF0\x9F\xA6\xBA";;

It's a trick question for Unicode awareness. It should show a service dog emoji but in my console, I see a dog followed by an orange vest. Here it is: 🐕‍🦺
