 I assume it is 'man-db' doing this.  When we used the original
'man' with 'groff' it used to do a lot of 'use the _proper_ symbol'
changes.

 Decoding the byte representations of UTF-8 back to U+nnnn form is
tedious - I used to have some notes on how to do it, from when I
found characters my font could not render, but it's easiest to look
online : www.utf8-chartable.de -
 in this case, the general punctuation in U+2000 to U+20FF.

 e2 80 90 U+2010 hyphen
 e2 80 98 U+2018 left single quote
 e2 80 99 U+2019 right single quote

 These are the preferred code points to use in text, any modern UTF-8
console font ought to be able to display them.  There are many other
U+2nnn glyphs in fairly-common use, my own fonts handle many of them
(by mapping multiple code points to a single glyph).  I'm not sure
if xinglp changed his font or just added UNICODE=yes ?

 I have some resources at linuxfromscratch in /~ken/fonts :
fonts-testing/alphabets-etc.txt (if reading it in firefox, it
continues to imagine this is encoded in Western European and has to
be told to use Unicode).

 The mapping of multiple code points to a single glyph can be
seen in the sigma tarballs (the .sfm files), or in the .psfu.txt
files within the LatGrkCyr tarballs, or in the uni-vga tarball which
showed me how to start creating my own fonts.
