I ended up looking at the spec (that's an hour I'll never get back!) and
it's more complicated...

Yes, I wasn't thinking.  Thanks.  You can't always tell until the second
byte, but you don't have to "unget" anything in that case because you
now know the character.

But as it happens I spoke way too soon...  The full picture is a mess.

What do you mean "when passed a string"?  Do you mean when the parser is
acting on in-memory data?

It turns out that if you want to be 100% conforming you need to be able
to detect both UCS-4 and (eye roll) EBCDIC.  What's more, you need to
set up just enough of the reading mechanism to be able to read the XML
declaration and then adjust the reading mechanism to handle the named
encoding.  For your application, ISO-8859-1 might be effectively the
same as ISO-8859-15, but UCS-4 is a complication and you might want to
flag certain errors if the encoding is named as ISO-10646-UCS-2 rather
than UTF-16.

While this can obviously be done in C, I would much rather do it in
Haskell.  Haskell's lazy evaluation gives you stream IO for free (so to
speak), and handling the tail of a lazy stream with functions computed
by looking at the start of it comes naturally in Haskell.
