Hi,
I've tried groff-ifying the Unifont, in the same way I do it with the
Tinos font. However, I've had a few problems.
Here's the Tinos font that's packaged with Debian:
$ apt-file find tinos | grep ttf
texlive-fonts-extra-links: /usr/share/texlive/texmf-dist/fonts/truetype/google/tinos/Tinos-Bold.ttf
texlive-fonts-extra-links: /usr/share/texlive/texmf-dist/fonts/truetype/google/tinos/Tinos-BoldItalic.ttf
texlive-fonts-extra-links: /usr/share/texlive/texmf-dist/fonts/truetype/google/tinos/Tinos-Italic.ttf
texlive-fonts-extra-links: /usr/share/texlive/texmf-dist/fonts/truetype/google/tinos/Tinos-Regular.ttf
And here's the Unifont:
$ apt-file find unifont | grep otf | grep fonts | grep -v japanese
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_csur.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_jp.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_jp_sample.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_sample.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_upper.otf
fonts-unifont: /usr/share/fonts/opentype/unifont/unifont_upper_sample.otf
First problem:
In the Unifont, I don't see a "Regular" font. I assumed I should take
the unifont.otf file.
Here's how I've been groff-ifying the Tinos font:
$ make build-fonts-tinos -B --debug=pretty
MKDIR .tmp/fonts/devpdf/
install -m 755 -d .tmp/fonts/devpdf/

Are any of those warnings something I should take care of? Or should I
just ignore them? If they're unimportant, can I ask that low severity
warnings not be printed? Or should I just 2>/dev/null?
Well, apart from those warnings, that works. Now, I repeat the process
with the Unifont:
$ make build-fonts-unifont -B --debug=pretty
MKDIR .tmp/fonts/devpdf/
install -m 755 -d .tmp/fonts/devpdf/
FONTFORGE .tmp/fonts/devpdf/Unifont.pfa
fontforge -lang=ff \
-c 'Open("/usr/share/fonts/opentype/unifont/unifont.otf");Generate(".tmp/fonts/devpdf/Unifont.pfa");'

Much nicer on stderr, which gave me hope at first.
But then I try to build the PDF book with both fonts.
$ grep -rh -e Tinos -e Unifont share/mk/build/pdf/book/
print ".pdfpagenumbering D . 1\n.nr PDFOUTLINE.FOLDLEVEL 0\n.defcolor pdf:href.colour rgb 0.00 0.25 0.75\n.pdfinfo /Title \"The Linux man-pages Book\"\n.special TinosR UnifontR S\n";
And I get a warning about the Unifont:
$ make build-pdf-book

Did I do anything wrong with the Unifont? I suspect of treating it as a
Regular font without any indication that I should.
(The Tinos changes are already in master. The Unifont changes are in
the contrib branch, since I'm not yet happy with them.)
Have a lovely day!
Alex
