Anyone,
I have been working on getting DWB troff (ditroff) to work
with an HP LaserJet II printer. I want to use the K font
cartridge as my font supply. Using Larry's (...!theceg!lkb)
makedev program I have generated the appropriate device
descripton files. The characters missing on the K cartridge I
simply left out. These included the hyphen \(hy, the rule
\(ru, the 3/4 \(34, the ligatures, and others. I quickly discovered
that the hyphen was necessary (no hyphens printed in hyphenated
text). After a lot of trouble I also discovered that the rule
must be there (otherwise troff will core dump when printing manual
entries).  Now my question:

Can anyone direct me to a minimal list of characters that
must be defined in order for troff to function correctly. Also,
what is the criterion (if any) for dividing these characters
between the standard and special fonts.
