Hi, I have written a couple of documents using plan 9's troff utility, but it can be safely assured that I am a troff newbie. Now I have to write some sort of manual, and I am using eqn(1) to write all the formulas and equations, but I ran into trouble as soon as I had to write a ≥ character. First of all I tried the eqn(1) approach, using something like $>= 1$ or $"" >= 1$ with $$ as delimiters. It did not work and produces a 'g 1' in the ps output. After a couple of attempts I decided not to use the eqn(1) approach and I moved to just the troff syntax, so I wrote '\(<= 1' to get the character, but no success, the output is still 'g 1'. Finally I remembered UTF so I just wrote '≥1', but again it failed, but this time with no output at all. Is this a bug in troff? and for me it raises a bigger question, isn't plan 9 and its utilities supposed to support UTF-8? Note that the command I am using is
9 eqn manual.ms | 9 troff -ms | tr2post > manual.ps I think that this is probably a bug in plan9's troff (or maybe I am doing something wrong) since with groff eqn manual.ms | groff -ms -Tps > manual.ps works just fine with the eqn(1) aproach and with the troff aproach. -- Saludos Hugo
