    I don't think we always contradict eachother! ;-)
    Indeed we seem to agree on that the TAG "characters"
    should be deprecated... [Long live the TAG BOLD and
    TAG ITALIC!; ah, no]

    ok. (And I don't think we disagree here at all.)

    I guess, fi, fl, etc. too.

    I'm not sure to what extent rendering systems "send" SHYs to fonts.
    If they do, then yes, such ligature table entries would be needed.
    If SHYs are handed before any characters are "sent" to the font (it
    would need to for proper interpretation, right?) they could also
    be removed before the string is "sent" to the font (or more generally,
    before automatic ligature processing).

    If, on the other hand, like (maybe!) for German, one want <f><SHY><f>
    and similar to not form a ligature in the graphical sense, one would
    have to somehow use special ligature entries or special letter forms
    for what originally was <f><SHY><f> (etc.) so that no ligature in the
    graphical sense would be formed, nor any ugly overlap.
