Does any of the fonts in the standard distributions of groff contain
characters depicting the standard male and female symbols?
(The circle with the oblique arrow above, and the circle with the cross
below.)
Inquiring minds would like to know.

Well, the .devicem macro will be exactly the same as \Y. To create

After some thinking I've now decided not to do this. Reason is that
we need a different mechanism for proper `' support. Currently,
groff emits a soft hyphen glyph only at line ends: With other words,
`' (or rather `') has never been emitted for

What is the real state of the troff land? What are the other
players beyond groff?
Some people still use the now defunct troff version of QuadSoft (many
syntactical extensions implemented in groff resemble its format), many
use Sun's troff (based on AT&T), and others rely on Plane 9's troff

When I was a youngster (yes!), device independence
and pre- and post-processors were good ideas and necessary. I
wonder whether it still is the case.
For me: definitely yes.
I concur.
Yes. You have PS/PDF and plain text (usually for man

You probably want something like this:
.de END
..
.
.de something
. de something-aux END
ps: exec \\$*
. END
\Y[something-aux]
..

.something 50 (hello)

The approach I took was to try and rename the .SH macro to som
