I thought they were appropriate for interchanging text as long as you
are in agreement with your associates as to how it should be
interchanged? What other purpose are there for PUA characters? (I am
aware some fonts put small caps letters in them, or other fancy styles
--- this is less than optimal and strictly unnecessary especially with
modern font formats like Open Type.) The CSUR would seem to be
appropriate for that. The only difficulty I am aware of is as you say:
