How to reproduce the behavior of SQL NVARCHAR in Python when generating a SHA-512 hash?

I have the following SQL query

SELECT CONVERT(VARCHAR(254), HASHBYTES('SHA2_512', CONVERT(NVARCHAR(24), '2020-05-27 00:00:00.000', 127)), 2)

​x
 
SELECT CONVERT(VARCHAR(254), HASHBYTES('SHA2_512', CONVERT(NVARCHAR(24), '2020-05-27 00:00:00.000', 127)), 2)​

that generates the hash value

out of todays date and I want to reproduce this hash in Python with

hashlib.sha512('2020-05-27 00:00:00.000'.encode()).hexdigest().upper()

 
hashlib.sha512('2020-05-27 00:00:00.000'.encode()).hexdigest().upper()​

but I get

as hash value. When I use VARCHAR instead of NVARCHAR I get the correct hash value. How can I reproduce the bahavior of NVARCHAR in Python?

Answer

NVARCHAR encodes to UTF-16LE. Adding it to

hashlib.sha512('2020-05-27 00:00:00.000'.encode('utf_16_le')).hexdigest().upper()

 
hashlib.sha512('2020-05-27 00:00:00.000'.encode('utf_16_le')).hexdigest().upper()​

creates the correct hash value.
