Support regarding input of unicode chars
Hi! Is there a way to use character U+2112 in my document? So far I have tried `\[u2112]`, which does seem to work for characters like `\[u0394]` that are listed in the groff_char manual.

One is to use groff's special character escape sequences as you showed above. Like this: $ cat ATTIC/2112a.groff They've taken care of everything! .rj \[em] \[u2112]\[u2112]\[u2118] .pl \n[nl]u $ nroff ATTIC/2112a.groff Another approach is to put UTF-8 in your source document, and then use the '-k' option to nroff or groff to run preconv(1). $ cat ATTIC/2112b.groff They've taken care of everything! .rj — ℒℒ℘ .pl \n[nl]u $ nroff -k ATTIC/2112b.groff In either case you get the same output. --snip--- They’ve taken care of everything! — ℒℒ℘ --end snip--- Does this work for you? Is there anything else we can help with? Regards, Branden signature.asc Description: PGP signature

Hi Gustavo, If you are going for terminal output, Branden has dealt with that. If you want PDF or Postscript output, I'm afraid you will have to do a bit of work. The problem is that the "Laplace transform" (U+2112) character is not present in groff's symbol font, so you need to install a suitable font to supply the glyph. On my system I found the glyph in a font:- /usr/share/fonts/opensymbol/opens___.ttf Since it is a truetype font I had to convert it to a type 1 font with fontforge and then run afmtodit to create a groff font file called OS. You may be able to use the install-font.sh script available at:- http://www.schaffter.ca/mom/mom-06.html Although the font should be installed as a symbol font rather than a text font and I'm not sure if the script handles that yet. After installation this works:- printf ".special OS\n\s'24'ℒ"|groff -k -ms -Tpdf > Laplace.pdf The result is attached. If you prefer I can send you the resulting fonts, plus instructions.
