``` xarray.Dataset({'x': ['foo', 'bar', 'baz']}).to_netcdf( 'foo.nc', engine='h5netcdf', encoding={'x': {'dtype': 'S1', 'zlib': True, 'chunksizes': (2, )}})

ValueError: "chunks" must have same rank as dataset shape ` Same withengine='netcdf4'``. The issue is present in 0.10.6 as well as in 0.10.3. The problem is obviously that dtype=S1 changes the shape of the variable before passing it to the backend, but while doing so doesn't also change an eventual chunksizes setting.

The workaround is to omit chunksizes or set it to True.
