Re: HELLO changes

    It isn't meaningful to say ??? is a `Unicode character' because I
    typed it with the TeX input method, but ??? isn't because I typed it
    with latin-9-prefix (assuming they don't get canonicalized on input).
    They are different representations of the same character (which should
    preferably actually be displayed the same).

Doesn't the current Emacs represent them with different codes,
treating them as different charsets?  That was the case until
recently, I think.

You added an option to unify them on input, but isn't that turned off
by default?
