Agreed, ASCII or no specified encoding, isn't much good these days,
but IMHO requiring utf-16 is too much.

I'm simply saying that a single encoding is too strict, too limiting.
for 80%, utf-8 may suffice, why constrain users?
Hence allow users to use their own encodings, but simply
require a declaration of that encoding.
