我正在尝试从Oracle数据库中提取数据，该查询工作正常，但是当我尝试将其传递给DataFrame时，会收到错误消息。
# -*- coding: latin-1 -*-
import pandas as pd
import cx_Oracle as cx_Oracle
dsn_tns = cx_Oracle.makedsn(r'****','***', service_name='*****')
conn = cx_Oracle.connect(user=r'***',password = '****',dsn=dsn_tns)
c = conn.cursor()
try:
query = '''

'''
alundisc = pd.read_sql(con = conn, sql = query)
finally:
conn.close()
每次运行代码时都会出现以下错误。
Traceback (most recent call last):
File "C:\Users\gilmar.melo\AppData\Local\Programs\Python\Python38\lib\site-packages\pandas\io\sql.py", line 1586, in execute
cur.execute(*args, **kwargs)
UnicodeEncodeError: 'ascii' codec can't encode character '\xf3' in position 632: ordinal not in range(128)
如果我不把alundisc = pd.read_sql（con = conn，sql = query）放在那行，代码就可以运行。
