M-: default-terminal-coding-system says utf-8-unix.  I haven't set this
in my site-start.el or .emacs.

I have my font set to Latin-1.  More precisely,

    consolefont="lat1-16"

in my /etc/conf.d/consolefont.

I will try, but I doubt that will bring anything.  It's such an obvious
thing to want that it must have been brought up in the Texinfo mailing
lists lots of times in the last few years.  I think the maintainer is
hostile to ASCII punctuation characters.

Like I said, if I want this fixed I'll probably need to fix it myself,
even if only for me personally.
