That would be because the notion of a BOM makes not much
sense at all for UTF-8. There is no byte order issue with
UTF-8, yet some brilliant mind thought it would be a good
idea to define and allow one (EF BB BF) anyway. And, pray
tell, other brilliant minds decided to use it as a way to
tell UTF-8 from traditional single byte encodings. This is
absurd, as it is just as bad as any other heuristic one
may come up with to deduce text file character encoding.
To add insult to injury, some poorly written text editing
tools insert a BOM without any need or even being asked to,
deliberately breaking otherwise perfectly fine 7-bit ASCII
files and rendering them incompatible to legacy software.
