Title: Support charset meta tag.

I know GH #3539 and #149.
But I want to propose it again, because I have another motivation.

I'm Japanese and resident in the multibyte world.
In my experience, if we don't write charset meta tag, we've got trouble in terms of the next.

If we save a page as html file.

When we open the html file, we'll miss a charset .
