Much as I don't like their uninvited use, it is possible to pass them
and other undesirables through most applications by a slight bit of
recoding at the application's boundaries. Using 99 = (3 + 32 + 64) PUA
characters, one can ape UTF-16 surrogates and encode:

32 64 pairs for lone surrogates
 1 64 pairs to replace some of the PUA characters
 1 35 pairs to replace the rest of the PUA characters
 1 4 pairs for incoming FFFC to FFFF
 1 32 pairs for the other BMP non-characters
 1 32 pairs for the supplementary plane non-characters.

This then frees up non-characters for the application's use.

Richard.
