Hmm, interesting!

I've avoided attrs since they often get "lost" in computation, and don't get dragged along as rigorously as coordinates.

I do have some real coordinates that are stored as strings.

Thanks for the quickfeedback.

Here is the reproducing code without using context managers (which auto clsoe things you know)

```python import xarray as xr import zarr x = xr.Dataset() x['hello'] = 'world' x with zarr.ZipStore('test_store.zip', mode='w') as store: x.to_zarr(store)

read_store = zarr.ZipStore('test_store.zip', mode='r')
x_read = xr.open_zarr(read_store).compute()

The error will happen before this line is executed

read_store.close()

```
