[whatwg] Default encoding to UTF-8?

> (And HTML5 defines it the same.)

No. As far as I understand, HTML5 defines US-ASCII to be the default and
requires that any other encoding is explicitly declared. I do like this
approach.

We should also lobby for authoring tools (as recommended by HTML5) to
default their output to UTF-8 and make sure the encoding is declared.  As
so many pages, supposedly (I have not researched this), use the incorrect
encoding, it makes no sense to try to clean this mess by messing with
existing defaults. It may fix some pages and break others. Browsers have
the ability to override an incorrect encoding and this a reasonable
workaround.
