It also says that form data should be encoded in the encoding of
the page where you fill in the form.

Well, communications takes two ends. Each server, for each
URI, has to decide what to do. If you want to make use of
the UTF-8 convention, you have to set your server side
accordingly.

This was a one-time ECMAScript solution. The ECMAScript standard now
has functions to support the UTF-8 convention.
The reason the %uXXXX was discontinued was that it's outside the
URI syntax, and therefore can break all kinds of things.
