For the reasons explained previously in this thread.  There are three
different character sets we are dealing with.  One is HTML, one is
MacRoman, one is ISO.  HTML uses numbers similar to ISO; � in ISO is
decimal 249, and in HTML is 249.  In MacRoman, it is 157.  If you have an
ISO font, type option-backtick-u (157) and option-shift-. (249) and switch
between ISO and MacRoman fonts.

What's needed is a Mac<->ISO translation or Mac<->HTML translation table,
which is not difficult to do, but it has to be done manually first and then
can be used over and again.
