This file has valid UTF-8 BOM mark, and it is UTF-8 encoded. Specified encoding
in a file is UTF-16, so it doesn't match BOM and actual encoding. If I
understand XML spec right this case should be considered as a fatal error for a
parser.

libxml2 does the following:

- detects input encoding using BOM;
- finds encoding attribute in xml declaration, UTF-16 for this file;
- encodings don't match and we didn't specify explicit encoding for parser
context, so it means a fatal error for it.

This clearly needs some tests to figure out a possible workaround for that,
I'll start with that. We did something similar for DOM parsing already, some
mess with default parser encoding.
