Oh shoot, you know, your fix kind of makes this test overlap with the round trip tests. Really the only purpose of this test is to make sure we're actually encoding things as JSON.

I think the proper fix is actually to only use single-item dictionaries in `KEY` and `VALUE`, so that there's only one way to encode them.

Alternatively, you could call `json.dumps()` directly:

```python
encoded = json.dumps(KEY) + '\t' + json.dumps(VALUE)
```
