By the way: In that case it is an illegal character per HTML5 as well: A UTF-8
document with a BOM would  be would bring the browser into Quirks-Mode if the
browser reads the document as - for example - ISO-8859-1.

So even if we look squarely at HTML5, it makes no sense to permit the encoding
to be overridden whenever there is a BOM: To permit the encoding to be
overridden when there is a BOM would be like permitting users to shoot
themselves in the foot.

PS: I now consider this subject to be debated to death. I am not going to give
any more explanations. And if I give any more replies, then they will be short
and to the point.
