Correct results can be obtained by using URLread

URLRead["https://zhuanlan.zhihu.com/p/35359905", "Body"]

But when using URLSubmit, the output is garbled

URLSubmit[
 HTTPRequest["https://zhuanlan.zhihu.com/p/35359905", 
  CharacterEncoding -> "UTF-8"], 
 HandlerFunctions -> <|"BodyReceived" -> ((body = #Body) &)|>]
