I vaguely remember looking into this before. I think the problem was
that there was no facility in Linux for determining whether a particular
character could be displayed on its console. The low level interface
simply wasn't there.

The Linux console is limited to 256 glyphs, some of which are used by two
or several Unicode characters. It would be possible but time consuming
to amend the font to display the EM-DASH as, say, a minus sign.

Again, this would only solve half of the problem, the display half, but
might be worthwhile. I would prefer, though, to find a way of preventing
these awkward Unicode punctuation charaacters from being in info buffers
in the first place.
