I think that James was talking about going from bytes representing a
Unicode character encoding, not a binary encoding.  There should be no
platform dependencies in that case.

In my experience, actual XML parsing generally takes so little time in
a real-world project that optimizing it to zero would still bring no
noticeable gain.  The only exception would be something dealing with a
constant, fat stream of XML data in real time (news feeds are too
low-volume to qualify).


All the best,
