[Heirloom] Using the Symbola font in Heirloom troff

(The heirloom-doctools README.md says to ask Heirloom doctools questions on this list.) I'd like to use the Symbola font in Heirloom troff. I tried the following: .do xflag 3 .\" fp 5 Optima Optima-Regular ttf .fp 5 Symbola S

Re: [Heirloom] Using the Symbola font in Heirloom troff

According to the Heirloom Troff manual, I think that you cannot just insert Unicode characters (although maybe if your LC* environment variables are set correctly, you can?). It says: > Both nroff and troff allow references to specific Unicode characters with the > \U'X' escape sequence; > it c

Re: [Heirloom] Using the Symbola font in Heirloom troff

And if I add "and explicit unicode character reference \U'1F0A1'" to the file, that character doesn't show up either. On Tue, Aug 4, 2020 at 2:47 PM Richard Morse wrote: > According to the Heirloom Troff manual, I think that you cannot just > insert Unicode characters (although maybe if your LC*

Re: [Heirloom] Using the Symbola font in Heirloom troff

Huh. I’m afraid I’m out of my depth then; you might check and see if your LC_* environment variables are set to something incompatible with utf-8 (or, maybe, check and make sure the file in UTF-8, not UCS-16 or something if you’re on Windows), but hopefully someone with more experience and knowl

In Emacs M-x describe-coding-system tells me the coding system for saving the buffer is utf-8-unix. I don't have any LC_* environment variables set, but LANG=en_US.UTF-8. I'm not very knowledgeable about the insides of Unicode fonts, unfortunately. On Tue, Aug 4, 2020 at 4:27 PM Richard Morse w

Re: [Heirloom] Using the Symbola font in Heirloom troff

Hm. Just for my edification, I tried a few things. I’m on a Mac, and I don’t know when I compiled Heirloom troff, but it was a year or two ago, so something things may be different. I downloaded the Symbola font from fontlibrary.org. The version I got was .ttf, not .otf. The various things tha

Thanks for the tip! As it turns out, I am using the OTF. On Wed, Aug 5, 2020 at 12:24 AM John Gardner wrote: > > The version I got was .ttf, not .otf > > I opened both the original OTF and the > FontLibrary.org > TTF in Gly

Re: [Heirloom] Using the Symbola font in Heirloom troff

Well, 0x fits in a unsigned short, two bytes. An unsigned int is 4 bytes, and 0x fits in it. I don't think that it is the size of the int that's the problem. On Wed, Aug 5, 2020 at 12:52 AM John Gardner wrote: > Going from the fact that unimap.c >

Looking at the postscript output there is a "/uni1F0A1 9429 def" and a "/uni1F10A" in a "/Encoding-@15@36 [...] def"; is that part of the font machinery? (I'm sadly ignorant of PostScript, alas.) Looking at troff/troff.d/otf.c
