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.
