    I think you're OK if you re-read what Deborah wrote:

    and just try to keep your PUA assignments down in the U+E000 "end user"
    end, and away from the U+F8FF "corporate use" end. Of course, if you
    have more than a couple thousand PUA characters, you may find out the
    hard way where Apple is drawing the line.
