Ideally the function signature would look like:

```python
def preprocess(ds, filename=None):
    ...
    return ds
```

This would avoid a breaking change and allow us to add additional kwargs at a later date if need be.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,378898407

```python
ds['varname'].encoding['source']
```

Presumably, you could unpack this via a preprocess step.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,378898407
