Availability:C-language interface function

const pl_wchar_t* PL_atom_wchars(atom_t atom, size_t *len)

Extract characters from a wide-character atom. Succeeds on any atom marked as‘text’. If the underlying atom is a wide-character atom, the returned pointer is a pointer into the atom structure. If the atom is represented as an ISO-Latin-1 string, the returned pointer comes from Prolog's‘buffer stack’(see section 12.4.14).
