Hello,

We are using code bellow to convert rst files to html.

Code works fine if we use old docutils version 0.20.1.

python -m pip install docutils==0.20.1

But current 0.22.3 version crashes.

import io
from docutils.core import publish_file

text = open('test.rst', 'rb').read()
source = io.BytesIO(text)
destination = open('test.html', 'w')
publish_file(source=source, destination=destination, writer_name='html')
destination.close()
source.close()

Traceback (most recent call last):
