After investigating the issue, it seems to be related to an error in the netcdf library, which in turn is related to an error in the hdf5 library. The relevant issues are

netcdf4: https://github.com/Unidata/netcdf4-python/issues/941 hdf5: https://forum.hdfgroup.org/t/non-english-characters-in-hdf5-file-name/4627/8

Quoting the dev responding in the hdf5 forum:

I would be thrilled to fix this issue. The problem is that it’s a huge amount of effort with no obvious funding source. Everyone wants this problem to be fixed but nobody wants it fixed so badly that they are willing to pay for an engineer to spend the better part of a year fixing it properly. A lot of people seem to think that we just need to tweak the “open file” code, but that isn’t true. So much stuff in the library is affected by Unicode file names on Windows and doing a hasty job will risk dramatically increasing our technical debt and bug count.
