the web are actually aliases for @code{windows-1252}, and a @code{UTF-8}
or @code{UTF-16} BOM takes precedence over any other encoding declaration.
The WHATWG @url{https://encoding.spec.whatwg.org/,Encoding} standard
defines all such details so that implementations do not have to
reverse-engineer each other.

This module implements the Encoding standard and has encoding labels and
BOM detection, but the actual implementation for encoders and decoders
