I meant that declaring UTF-8 is not generally applicable, because R
doesn't always output UTF-8 (right?). For example, locales that use
exotic encodings might output characters that are not interpretable
where UTF-8 is assumed.

The general solution, I suppose, is to automatically generate the
<meta /> line with the encoding used by R.
