Both XML and DOM are UTF-16 centric....for some pretty good implementation
reasons... which is why I pointed out the use of UTF-16 internally to the
parsers. I suggest UTF-8 as a storage medium for a variety of reasons,
mostly to do with differences in client and file-server processor
architecture, database support for Unicode, and other file-centric reasons.
The parser will decode UTF-8 (or any encoding that it supports and that you
declare) into its internal format, usually UTF-16 or UCS-4.

As for the BOM... it was my morning for typos.

utf-16-centric: utf-8 is one of the two default encodings (utf-8 & utf-16),
but text offsets are defined in terms of utf-16 code units, as far as i
know. i would expect most parsers to use utf-16 internally.
