The special meaning ones like units, _FillValue or long_name?

In general xarray is quite relaxed on what users put into the attrs, internally it is simply a dict of anything (see e.g. #7111 where people put in recursive DataArrays).

As soon as you try to write it into a netCDF it has to be serializable, but that's why it raises an error.

Personally I think the current behavior is fine (ofc, plotting etc should be able to deal with non-standard units etc.)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1388326248
