+     "In order to be compatible with legacy web content when interpreting
+something like @code{Content-Type: text/html; charset=latin1}, tools need
+to use a particular set of aliases for encoding labels as well as some
+overriding rules.  For example, @code{US-ASCII} and @code{iso-8859-1} on
+the web are actually aliases for @code{windows-1252}, and an @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
+is Python’s.")
