Deborah,
Could you please clarify what this means in practice? If I have a
document that uses PUA codepoints, and I have a font that I have been
using to display them, what will happen when I install the Panther
upgrade I just received? Based on what Dean Snyder wrote, it sounds
like my document may not display correctly any longer.
Thanks - David
