```python
In [1]: import xarray as xr
 
In [2]: import numpy as np

In [3]: ds = xr.Dataset({""1"": xr.DataArray(np.zeros(3), dims=[""a""], coords={""a"": list(""xyz"")})})

In [4]: ds
Out[4]: 
<xarray.Dataset>
Dimensions:  (a: 3)
Coordinates:
  * a        (a) <U1 'x' 'y' 'z'
Data variables:
    1        (a) float64 0.0 0.0 0.0

In [5]: ds[""2""] = xr.DataArray(np.zeros(2), dims=[""a""], coords={""a"": list(""xy"")})

    2        (a) float64 0.0 0.0 nan

```

I tested this with

```python
xarray: 0.17.0
pandas: 1.2.3
numpy: 1.20.1
```

Should we close this?

We do end up converting from fixed width strings to object quite often (to get around limitations of NumPy's strings), but adding in a variable should not change the type of any existing variables.

It's possible the best fix here will be to convert all string arrays into an object type as soon as they are loaded into xray objects.
