spell_checker.check()을 하기 전에 필요한 전처리가 무엇인가요?

[kwhkim]

x = ' 관심 0&※ 간섭 있습니다'
 spell_checker.check(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/kwhkim/opt/miniconda3/envs/py38spacing/lib/python3.8/site-packages/hanspell/spell_checker.py", line 68, in check

문제는 &인 것 같은데, 문자열에 사용할 수 없는 문자가 있나요?
