You *must* do so, unless the document is in UTF-8 or UTF-16. US-ASCII,
which is a subset of UTF-8, will also work, but ISO 8859-1, or KOI-8R,
or EUC-JP, is illegal without an encoding declaration or the equivalent
charset declaration on a MIME header.

The only default charsets are UTF-8 and UTF-16.

We are not talking about invalid characters (such as U+0001) which are
already fatal errors. We are talking about invalid encodings.
An FF byte in a UTF-8 document means the document is nonsense; there
is no telling what it means.
