Franck designed this class, so he can give the authoritative answer,
but the obvious design is that the BOM never appears in the stream at
all - it is consumed as part of the encoding detection.

The position indicated by XM_POSITION is in terms of unicode
characters, not bytes in the file, I would think. But we better wait
for Franck to answer.
