Pymssql controls SQL for Chinese queries

The phenomenon and background of the problem

pymssql control SQL The result cannot be found during Chinese query , however SQL Statements in SSMS Results can be found in

Problem related code , Do not paste screenshots

import SQL_part
if name == 'main':
con,cur=SQL_part.ConDataBase()
print(SQL_part.Select_Plate(cur,' Wan A4K1PS'))

Test functions

def Select_Plate(cursor,plate):
sql = "SELECT * FROM LicensePlate where plate='%s'"%plate
cursor.execute(sql.encode('cp936'))
return cursor.fetchall()
Query function

SQL sentence
SELECT * FROM LicensePlate where plate=' Wan C45K23'

Operation results and error reporting contents

No error reported , But there was no expected result

My solution ideas and tried methods

Consider maybe SQL Coding Chinese problems , But another query function can get results normally , And in ssms in sql Statements can be run

What I want to achieve

Can get Chinese keyword query results

Take the answer ：

Probability is a matter of character set , Please confirm the consistency of file code and character set .
in addition , Try to put cp936 Switch to cp65001, The one in front is ansi（GBK）, The back is utf8
