The default varies by localization (and within that potentially by
platform), and unfortunately that variation does matter.  You can
see Firefox's defaults here:
(The localization and platform are part of the filename.)

I changed my Firefox from the ISO-8859-1 default to UTF-8 years ago
(by changing the "intl.charset.default" preference), and I do see a
decent amount of broken content as a result (maybe I encounter a new
broken page once a week? -- though substantially more often if I'm
looking at non-English pages because of travel).

The more complex the rules, the harder they are for authors to
understand / debug.  I wouldn't want to create rules like those.

I would, however, like to see movement towards defaulting to UTF-8:
the current situation makes the Web less world-wide because pages
that work for one user don't work for another.

I'm just not quite sure how to get from here to there, though, since
such changes are likely to make users experience broken content.
