This should fix the `bytes` issue.  

But It seems that converting to string objects is by design (using ""netcdf4"").

```python
coils = np.array([""A"", ""B"", ""C"", ""D"", ""E""])
test_ds = xr.Dataset()
test_ds.coords[""coils""] = coils
print(test_ds)

> <xarray.Dataset>
> Dimensions:  (coils: 5)
> Coordinates:
>  * coils    (coils) <U1 'A' 'B' 'C' 'D' 'E'
> Data variables:
>    *empty*

test_ds.to_netcdf(""test_netcdf4.nc"", engine=""netcdf4"")
del test_ds
test_ds = xr.open_dataset(""test_netcdf4.nc"", engine=""netcdf4"")
print(test_ds)

> <xarray.Dataset>
> Dimensions:  (coils: 5)
> Coordinates:
>  * coils    (coils) object 'A' 'B' 'C' 'D' 'E'
> Data variables:
>    *empty*

@mathause Would you mind having a look at the proposed changes, also with respect to the implications for xarray? ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,800678839
