Replace `self._encoding` with `None` here? https://github.com/pydata/xarray/blob/ddc352faa6de91f266a1749773d08ae8d6f09683/xarray/core/variable.py#L1084","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,837243943

How does that work? 

There's a subtle difference. It drops all of `.encoding` not `dtype` specifically.

@shoyer's point about indexing changing chunking is a good one too. Perhaps a kwarg in `to_zarr` like `ignore_encoding_chunks`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,837243943
