An iterator to an NTCTS? That's an interesting invention. :-)

See http://beman.github.io/ntcts_iterator/

That's not the same. This takes a _pointer_ to NTCTS and creates an iterator range from it. The Filesystem wording in N3940 takes an _iterator_ to NTCTS. list<char> x{ 'a', 'b', '\0' }; l.begin(); // iterator to NTCTS http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3940.html#path-Requ... •A type meeting the input iterator requirements that iterates over a NTCTS. The value type shall be an encoded character type. A function argument Source const& source shall have an effective range [source, end) where end is the first iterator value with an element value equal to iterator_traits<Source>::value_type(). I've never encountered such a thing in the wild. Hence "interesting invention". :-)
