Universal-character-names are interpreted when transitioning
the lexical representation of a string-literal into an object
containing code units [lex.string], or when lexing tokens
outside of string-literals in translation phase 3 [lex.phases].

Nothing will interpret universal-character-names (as such) in
a string_view, because it is already assumed to be a range of
code units.
