This doesn't work with SCO's Text Processing System.  The nroff tables
are generated by a different method, and '%' is not accepted.  The
"trigger character" approach I am using is kind of similar.  Instead
of '%', I use '\177'.  The kludge is that you need the filter on the
output to translate back to 8-bit characters.  But, there is no pain
involved here, because I already need to run that filter to do my
overstriking.

The problem which still remains is that col(CT) munches the non-printing
characters.  So I can either get greek characters or I can get tbl tables,
but not both.  Hey SCO...with all this internationalization hype, why not
make the text processing system work for 8-bit characters?
