      WARNING: A dirty performance hack!
      Assuming the `i8` vectors in our implementations are just integers,
      and generally contain scalars in the [0, 100] range, we can transmit
      them as JSON-embedded strings. The only symbols we must avoid are
      the double-quote '"' (code 22) and backslash '\' (code 60).
      Printable ASCII characters are in [20, 126].
