read_csv() dtype=str is yielding <U0 instead of object

[ChuckConnell]

I want to import all my data as string columns, then convert the datatypes manually later. I am using the code shown below. It works correctly, all the data values seem OK. But I thought that the datatypes should be reported as 'object'. Instead they are all <U0.

Is this just terminology (<U0 is the same as object) or did I do something wrong?

CountyCovidKDF = ks.read_csv("/FileStore/tables/chuck1/County.csv", sep=',', header='infer', dtype=str)
CountyCovidKDF.info()

Data columns (total 6 columns):
 #   Column                               Non-Null Count  Dtype
---  ------                               --------------  -----
 0   Date                                 2145 non-null   <U0  
 1   County                               2145 non-null   <U0  
 2   New Confirmed Cases                  2145 non-null   <U0  
 3   Total Confirmed Cases                2145 non-null   <U0  
 4   New Probable and Confirmed Deaths    2145 non-null   <U0  
 5   Total Probable and Confirmed Deaths  2145 non-null   <U0
