Why didn’t you include “Unicode Scalars”, aka “well-formed UTF-8”, aka “the Swift string type?”
Either way, I think the bitter lesson is a parser really can’t rely on the well-formedness of a Unicode string over the wire. Practically speaking, all wire formats are potentially ill-formed until parsed into a non-wire format (or rejected by same parser).
