Postgresql – UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 61: invalid continuation byte

Why I have problem like that? How did you solve that? I am trying to connect to postgresql

import psycopg2

conn = psycopg2.connect(database="test", user="postgres", password="260508", host="localhost", port="5432")
print("Database Connected....")

in result i have error.

Traceback (most recent call last):
  File "C:UsersgamerDesktopPyCharm WorkspacePyCharm WorkspaceSQL TestSQL Testmain.py", line 3, in <module>
    conn = psycopg2.connect(database="test", user="postgres", password="260508", host="localhost", port="5432")

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 61: invalid continuation byte

I was trying to decode and encode like that

import psycopg2
import base64

password = "260508".encode('utf-8')  # Encode directly to UTF-8
encoded_password = base64.b64encode(password).decode('utf-8') 

conn = psycopg2.connect(database="test", user="postgres", password=encoded_password, host="localhost", port="5432")
print("Database Connected....")
