Expand usage of defaultEncoding in HttpBody in the http_server package.

Expand usage of defaultEncoding in HttpBody in the http_server package.

This fixes a few cases where other default encodings was used. Given
that we operate with the concept of a default encoding, to use that
encoding makes more sense.

Maybe add a link to the HTML5 spec for this, and mention that the use of the
page encoding or accept-encoding on the form cannot be detected in the response,
but needs to be specified through defaultEncoding.
