None of that matters for the case in point.  The C code treats the input
like a stream of 8-bit bytes.  You can do that without regard to line
convention.

Again, that's not relevant to the case in the article.  But it's also a
completely different issue.  An XML parser that must handle either UTF-8
or UTF-16 needs a layer below the parser (conceptually) to detect the
encoding and return "characters" (as I think you have done).  There is
no reason to suppose that that can't be written in portable C.

Exactly -- though I think I would not have converted to UTF-8 in a plain
parser.  Maybe your application make that a good choice.

The first character much be '<' (and, technically, it must be the '<' that
opens an XML declaration).  The encoding should be clear from the first
two bytes.

Actually, you don't need to read more that one character to determine if
the file is UTF-8 or UTF-16, all you need to do is an ungetc call and
that works on non-seekable streams.

Given that you convert UTF-16 to UTF-8, I'd have thought it was the
natural choice, even though you can get away with just an ungetc
call.  But then I don't know how your code is organised.  What's fiddly
about it?

Agreed.  Though I don't think the world is that good at agreeing things.
It's possible that this is not what the author had in mind with the
high/low-level portable code remark, but it's not a clear-cut case.  When
the world has decided that a text file can just be opened and read, such
a facility could be provided by standard C, and even if not standard, it
could probably be written in portable C.
