Sorry if this has been answered already elsewhere in the thread. 
The XML specification has a guideline for detecting the source encoding:

http://www.w3.org/TR/xml/#sec-guessing

and this is basically what parsers do.  One-byte encodings are 
basically indistinguishable from each other and they could be only 
reliably detected in presence of an explicit encoding 
information/declaration.
