a console font can only contain 512 glyphs (including bold variations of
the same character).

there's space to add another couple of glyphs to lat1-16? GCC spits out
some '?' too, when it prints some fancy warnings out, so it'd be nice to
get that symbol added, while we're at it.

I no longer remember how to look at .psfu files - in the past, I googled
for something like "psf file format" and found enough to be able to read
whatever I was looking for. I know that the current kbd maintainer takes
patches, but I don't know how to edit these fonts. I'm guessing fontforge
might be the right tool.
Sigma-consolefonts maps U+2010 (hyphen), as well as U+2012, U+2013,
U+2212, to U+002D (minus sign) in all of the screen font maps except
'drdos'. Possibly, you can do the same addition of multiple characters
for the same glyph using 'dd' once you've worked out the format ;-)
The attachment is the prog I wrote to list what was in a psf. Dunno if it
will help.
As to whether the book should use sigma-consolefonts, I have no idea. I'm
sure many people will hate the output, either because it is a lot less
bold, or because the more useful mappings are 512-byte and that screws up
their bold colours.
I haven't looked at the trunk version of the book yet, but previously we
used to do
{{{
sed -i -e 's/2010/002D/' -e 's/2212/002D/' \
-e 's/2018/0060/' -e 's/2019/0027/' font/devutf8/R.proto
}}}
before we configured groff to get rid of these awkward characters.
