```python
import xarray
import numpy as np

name = 'loc_techs_export'
data = np.array(['foo::bar'], dtype=object)
data_array = xarray.DataArray(data, dims=[name], name=name, coords={name: data})
print(data_array)  # looks identical to your example
data_array.to_netcdf('test.nc', engine='netcdf4')  # works
```

Can you share how you save the file to disk? A reproducible example would help greatly here.

Is there anything in the `encoding` attribute for this variable, or in the `encoding` keyword argument to `to_netcdf`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,357729048
