I wrote and use a string_ref class.  I made no attempt to support wchar_t.  It provides a constructor for std::vector<char>, besides the constructors given in N3334.  I also have a const_substring type for which there's a constructor.  The list can grow large, of course, so relying on conversions to string_ref from other string-like types is reasonable.

I don't agree with replicating std::string's too large interface in string_ref.  I'd prefer to use free functions to augment the functionality.

They support that for string_ref, but not array_ref.  Go figure.
