|Can [nt]roff use 8-bit charactercodes now when Sunos is (almost) SYSV? | -- jh at efd.lth.se (Joergen Haegg) No, unfortunately. Nroff and troff are listed as being 8-bit dirty (SunOS 4.1 Release Manual, table 7-4). They still strip the top bit on input. SunOS 4.1 still uses the old troff, not ditroff.
