When the wrapped array is a scalar string, indexing with an empty tuple doesn't work properly:
```
In [14]: from xarray.core.indexing import CopyOnWriteArray, MemoryCachedArray
In [15]: x = CopyOnWriteArray(np.array([1, 2, 3]))
In [16]: x[0]
Out[16]: CopyOnWriteArray(array=1)
In [17]: x[0][()]
Out[17]: CopyOnWriteArray(array=1)
In [18]: x = CopyOnWriteArray(np.array(['foo', 'bar']))
In [19]: x[0]
Out[19]: CopyOnWriteArray(array='foo')
In [20]: x[0][()]

TypeError Traceback (most recent call last)

----> 1 x[0][()]

402 def __getitem__(self, key):
--> 403 return type(self)(self.array[key])
404
405 def __setitem__(self, key, value):
TypeError: string indices must be integers
```
In some sense, the source issue is that `x[()]` works for numpy scalar numbers, but not strings.
I will see if I can come up with an elegant fix...","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,221855729
