Regarding the handling of the Accept-Encoding header field, https://tools.ietf.org/html/rfc7231#section-5.3.4 states:
A request without an Accept-Encoding header field implies that the user agent has no preferences regarding content-codings. Although this allows the server to use any content-coding in a response, it does not imply that the user agent will be able to correctly process all encodings. I would conclude that libcurl should still try to decompress a response with a supported Content-Encoding, however Curl_http_readwrite_headers() explicitly checks if data->set.str[STRING_ENCODING] was set (i.e. an Accept-Encoding header was sent), and therefore disables compression. I would simply remove that check for STRING_ENCODING.
