guyben c25f765fc5 Set the MIME type BEFORE the payload
When we set the payload, it is converted to bytes using the response's
character set. Changing the MIME type later has no effect on the conversion
to bytes, even though it does change the returned MIME type. This results in
bytes that were encoded using one character set while the response reports a
different character set.
