I made it say in

C.2.  Percent Encoding

    Some user agents accept percent encoded ([RFC3986], Section 2.1)
    sequences of characters.  The character encoding being used for
    decoding depends on various factors, including the encoding of the
    referring page, the user agent's locale, it's configuration, and also
    the actual value of the parameter.

    In practice, this is hard to use because those user agents that do
    not support it will display the escaped character sequence to the
    user.  For those user agents that do implement this it is difficult
    to predict what character encoding they actually expect.

That should be more correct, but I welcome corrections from those people 
who may be able to describe more precisely what the two UAs actually do.

Best regards, Julian
