Declared <https://github.com/python/cpython/blob/main/Lib/xmlrpc/server.py#L622>
Inside
[`do_POST()`](https://github.com/python/cpython/blob/main/Lib/xmlrpc/server.py#L493)
`data: bytes`, where `decode_request_content()` only handles `gzip`
compression.
The `result` is then written to `self.wfile`, which uses `bytes`.
But for
[CGI](https://github.com/python/cpython/blob/main/Lib/xmlrpc/server.py#L636)
`str` is used: [`handle_xmlrpc(self,
request_text)`](https://github.com/python/cpython/blob/main/Lib/xmlrpc/server.py#L642)
calls the argument `request_text`, which is read from `sys.stdin` as
type `str` and then passed to `_marshaled_dispatch()`, which internally calls
[`xmlrpc.client.loads()`](https://github.com/python/cpython/blob/main/Lib/xmlrpc/server.py#L257)
to parse the XML using Expat, which accepts both `str` and `bytes`; the
later defaults to encoding `utf-8`, but other encodings can be
used when explicitly specified:
>>> xmlrpc.client.loads('<params><param><value><string>ä</string></value></param></params>')
(('ä',), None)
>>> xmlrpc.client.loads('<params><param><value><string>ä</string></value></param></params>'.encode("utf-8"))
(('ä',), None)
>>> xmlrpc.client.loads('<params><param><value><string>ä</string></value></param></params>'.encode("iso-8859-1"))

the `rfile` and `wfile` members are already implemented by
StreamRequestHandler. In addition to them several (undocumented)
class and instance variables exist according to
<https://github.com/python/cpython/blob/master/Lib/socketserver.py#L742>:
- `rbufsize`
- `wbufsize`
- `timeout`
- `disable_nagle_algorithm`
- `packet` and `socket` for datagrams
The already exist with Python 2.7
