I don't think the test should fail although I'm not sure what the `np.str_` type actually is so maybe this isn't a bug? Help/advice greatly appreciated.

What problem are you trying to solve here?

This vlen string stuff is an internal API that isn't really intended for use outside Xarray.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,877016428
