Paraview Cannot load VTKHDF file that contains string Datasets

I write vtk files as vtkhdf and I’ve come across a problem loading strings in Paraview. I’m not sure if this is a ParaView, vtkhdf or general hdf5 problem.

I’ve taken the vtp map example from the online test files and created a vtkhdf version of it.
map_base64.vtp (2.5 MB)
map.vtkhdf (2.0 MB)

I can open the vtkhdf file in any hdf5 fileviewer so I believe the issue lies in one of ParaView or the vtkhdf attributes for string datasets.

Hello, string cell and point field values are not currently supported by VTKHDF.
