I would think that deserialization would be an operation on a Range of
std::byte or int8_t, where you would read out code points depending on the
encoding. Possibly with either replacement or failure. But until you have
code points, it's not text, it's raw octets. [Are we still supporting the
hypothetical 9 bit byte computer in the standard?]
