Thanks Peter, That's how it used to work.
I have Pages '09, Mac OS Lion 10.7.5.
i.e. I used to use Special characters to find/access all possibilities within Zapfino.
Now I can see four variations on an "A" through Font Book > Repertoire.
Don't have any way to access them.
Pages>Special Characters shows me all "A"' in assorted fonts, only one in Zapfino.
Pages still plugs in assorted variations on characters as I type, I just can't select them myself.
I've looked for possible solutions, still searching. Any help is appreciated.
