I'm ambivalent about whether we should restrict to utf8 or not. On the one
hand, having everyone on utf8 would greatly simplify the web. On the other
hand, I can imagine this hurting download size for japanese/chinese
websites (i.e. they'd want utf-16).

I agree with Boris that we don't need to pollute the web if we want to
expose this to WebKit's walled-garden environments. We have mechanisms for
exposing things only to those environments specifically to avoid this
problem. Lets keep this discussion focused on what's best for the web. We
can make WebKit do the appropriate thing.
