    The components of a URL are broken down like this:

       https://jo%40email.com:a%20secret@müller.de:1234/pa%20th?search=ab#anchorlink
    [scheme]   [  username  ] [password] [ host ][port][ path ] [ query ] [fragment]
               [       userinfo        ] [   netloc   ][    raw_path    ]

    Note that:

    * `url.scheme` is normalized to always be lowercased.

    * `url.host` is normalized to always be lowercased. Internationalized domain
      names are represented in unicode, without IDNA encoding applied. For instance:

      url = httpx.URL("http://中国.icom.museum")
      assert url.host == "中国.icom.museum"
      url = httpx.URL("http://xn--fiqs8s.icom.museum")
      assert url.host == "中国.icom.museum"

    * `url.raw_host` is normalized to always be lowercased, and is IDNA encoded.

      url = httpx.URL("http://中国.icom.museum")
      assert url.raw_host == b"xn--fiqs8s.icom.museum"
      url = httpx.URL("http://xn--fiqs8s.icom.museum")
      assert url.raw_host == b"xn--fiqs8s.icom.museum"

    * `url.port` is either None or an integer. URLs that include the default port for
      "http", "https", "ws", "wss", and "ftp" schemes have their port
      normalized to `None`.

      assert httpx.URL("http://example.com") == httpx.URL("http://example.com:80")
      assert httpx.URL("http://example.com").port is None
      assert httpx.URL("http://example.com:80").port is None

    * `url.userinfo` is raw bytes, without URL escaping. Usually you'll want to work
      with `url.username` and `url.password` instead, which handle the URL escaping.

    * `url.raw_path` is raw bytes of both the path and query, without URL escaping.
      This portion is used as the target when constructing HTTP requests. Usually you'll
      want to work with `url.path` instead.

    * `url.query` is raw bytes, without URL escaping. A URL query string portion can
      only be properly URL escaped when decoding the parameter names and values
      themselves.
