It's a quoted symbol when it appears in a docstrin= g, just=20 as `foo-bar' is a quoted symbol. Of course there are exceptions when the= quotes=20 are themselves escaped, but similar exceptions apply to ASCII quotes. In practice, curved quotes are a bit less ambiguous than ASCII quotes, be= cause=20 one can easily use them to quote any ASCII-only Lisp code, and this is so= mething=20 that ASCII quotes can't do.
