我是爲了測試我的Web應用程序，從/ dev /隨機到我的網頁前端。此行拋出一個錯誤：從/ dev /隨機引發lxml中的錯誤的隨機文本：所有字符串必須與XML兼容：Unicode或ASCII，無NULL字節
print repr(comment)
import html5lib
print html5lib.parse(comment, treebuilder="lxml")
'a\xef\xbf\xbd\xef\xbf\xbd\xc9\xb6E\xef\xbf\xbd\xef\xbf\xbd`\xef\xbf\xbd]\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd2 \x14\xef\xbf\xbd\xc7\xbe\xef\xbf\xbdy\xcb\x9c\xef\xbf\xbdi1O\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbdZ\xef\xbf\xbd.\xef\xbf\xbd\x17^C'

我犯了用戶輸入的字符串之前，我這樣做：
comment.decode（ 'UTF-8'）編碼（ 'UTF-8'， 「替換」）
但這似乎沒有幫助在這種情況下。
