    One might say that surrogate pairs (and triples and quadruples) existing
    in UTF-8, though of course Surrogate Pairs -- in the UTF-16-specific
    sense -- do not. UTF-16 Surrogate Pairs are basically doing the same
    thing that multi-byte sequences in UTF-8 do: provide a coding mechanism
    to represent a larger range of code points than could nominally be
    represented by the code units of the given encoding form directly (256
    for 8-bit code units and 65536 for 16-bit code units). They mainly
    differ only in details.
