```python
import xarray as xr

ds = xr.Dataset(
    data_vars={""foo"":([""x""], [False, True, False])},
    coords={""x"": [1, 2, 3]},
)
ds.to_netcdf('test.nc')
ds = xr.load_dataset('test.nc')
print(ds.foo.dtype)
ds.to_netcdf('test.nc')
ds = xr.load_dataset('test.nc')
print(ds.foo.dtype)
```
Gives:
```
