lxml can not parse xml (wether encoding is utf-8 or not) [python]

My code:

import re
import requests
from lxml import etree

url = 'http://weixin.sogou.com/gzhjs?openid=oIWsFt__d2wSBKMfQtkFfeVq_u8I&ext=2JjmXOu9jMsFW8Sh4E_XmC0DOkcPpGX18Zm8qPG7F0L5ffrupfFtkDqSOm47Bv9U'

r = requests.get(url)

items = r.json()['items']
  1. without encode('utf-8'):

etree.fromstring(items[0]) output:

ValueError                                
Traceback (most recent call last)
<ipython-input-69-cb8697498318> in <module>()
----> 1 etree.fromstring(items[0])

lxml.etree.pyx in lxml.etree.fromstring (src\lxml\lxml.etree.c:68121)()

parser.pxi in lxml.etree._parseMemoryDocument (src\lxml\lxml.etree.c:102435)()

ValueError: Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration.
  1. with encode('utf-8'):

etree.fromstring(items[0].encode('utf-8')) output:

  File "<string>", line unknown
XMLSyntaxError: CData section not finished
鎶楀啺鎶㈤櫓鎹锋姤:闃冲寳I绾挎, line 1, column 281

As a workaround, you can remove encoding attribute before pass the string to etree.fromstring:

xml = re.sub(r'\bencoding="[-\w]+"', '', items[0], count=1)
root = etree.fromstring(xml)

UPDATE after seeing @Lea's comment in the question:

Specify parser with explicit encoding:

xml = r.json()['items'].encode('utf-8')
root = etree.fromstring(xml, parser=etree.XMLParser(encoding='utf-8'))
