Btw, aren=E2=80=99t there any ways of, at least locally, extending/redefini= ng such reader behavior such as the one of =E2=80=9C'=E2=80=9D, =E2=80=9C,=E2= =80=9D/=E2=80=9C,@=E2=80=9D, =E2=80=9C`=E2=80=9D, =E2=80=9C.=E2=80=9D, =E2= =80=9C:=E2=80=9D, etc.? For instance to experiment having such fancy and strange quotes in source code: people really wanting to use it *might* want to use it as such, instead of symbol component, which, inside ascii, often (with a lot of exceptions such as in =E2=80=9C!=E2=80=9D, =E2=80=9C?=E2=80=9D, =E2= =80=9C:=E2=80=9D (though it can have special meaning) or =E2=80=9C.=E2=80=9D (though this one doesn=E2=80=99t work alone= ) other non-human-text =E2=80=9Cpunctuation=E2=80=9D (also named =E2=80=9Cspecial c= haracters=E2=80=9D) such as in =E2=80=9C%&*+/<>=3D@^_|=E2=80=9D) cannot be part of a symbol without esc= aping (for instance: =E2=80=9C"#'(),;\[]`=E2=80=9D (though this is tiny, it is not tha= t simple)).
