将postgres表导出为csv会得到UnicodeEncodeError

Question

我有上面的代码，它将Postgres表复制到csv文件。

cur = db.cursor()
q = "COPY (select * from assessments) TO STDOUT WITH CSV DELIMITER ';' ENCODING 'UTF-8'"
with open("table.csv", "w") as file:
    cur.copy_expert(q, file)
cur.close()

尽管如此，当我运行它时，出现以下错误：

Traceback (most recent call last):
  File "postgrestocsv.py", line 31, in <module>
    cur.copy_expert(q, file)
  File "C:\Users\andri\Anaconda3\lib\encodings\cp1253.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u202f' in position 343: character maps to <undefined>

有人可以帮助我了解问题所在吗？感谢您能提供的任何帮助
