For a generic function that handles arrays:

template < typename T, std::size_t N >int  hash( const T (&x)[N] );

It should do all elements.  An array of char or wchar_t (or the new C++11 character types) may not be astring, a conceptual whole; it could be a collection of independent objects, like any other element type.
