UTF-8 detection is reliable if the detector has the entire byte stream
available at the time of detection. It would be feasible to make it so
for file: URLs. But not for http[s] URLs.

In other words, you can't detect UTF-8  reliably when you've only seen
one KB of plain ASCII bytes, you need to commit to an encoding that
<link rel=stylesheet>s and <script src>s within that first KB of HTML
will inherit and you don't yet know what kind of bytes are later in
the stream.
