url-retrieve-synchronously and coding

[Lennart Borgman]

If I do something like this

         (setq buffer (url-retrieve-synchronously url))

and the contents of the buffer begins with

  HTTP/1.1 200 OK
  Content-Type: text/xml
  X-Content-Type-Options: nosniff
  Connection: close

  <?xml version = "1.0" encoding="UTF-8" standalone="yes"?><!--

  Content-type: fix-mhtml
  -->

should not then the buffer file coding system be utf-8?

This does not happen for me, but I am unsure if this is a bug or not.
