(see https://github.com/zarr-developers/zarr-specs/issues/6). But zarr definitely does  support variable length strings now (https://zarr.readthedocs.io/en/stable/tutorial.html#string-arrays), and I think it would be pretty easy to support in xarray, too.

You'd need to set `allows_unicode=True` here:

and then be sure to pass in `dtype=str` when constructing the zarr array (see `_nc4_dtype` in the netCDF4 backend for an example of this)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,404119432
