It seems like zarr is inserting `VLenUTF8` as a filter, but the loaded data array already has that as a filter so it's trying to double encode . So another workaround is to delete the filters on `site_code`:

```
import xarray as xr

sm_from_zarr = xr.open_zarr('tmp/test_sm_zarr')
del sm_from_zarr.site_code.encoding[""filters""]
sm_from_zarr.to_zarr('tmp/test_sm_zarr_from', mode='w')
