The distinction between an N-dimensional array of chars and an
(N-1)-dimensional array of fixed-length strings is pretty subtle, and it
looks like we assumed you could use the former if you needed the latter.
Multidimensional arrays of chars are supported in netCDF-4 just as in
netCDF-3. Maybe a few convenience functions that treat an N-dimensional
array of chars as an (N-1)-dimensional array of strings that happen to
be fixed length are all that's needed. If not, we may need a more
detailed use case that would make clear why that's inadequate.
