This was only a partial fix, because fonts that don't have a build-in
Unicode map were still defective.
So I made a patch to update all unimaps files (so the 'data/unimaps'
folder).
You can get it here: http://malaria.perso.sfr.fr/kbd/unimaps.patch

I also made a tar.gz with an updated 'data/consolefonts' folder (thanks
to my script). You can download it here:
http://malaria.perso.sfr.fr/kbd/updated_consolefonts.tar.gz

So, basically, if you apply this patch and replace all fonts by their
updated version, then your KBD will support all Unicode spaces (and so
the 'narrow no-break space' which is the one I primarily want).


You can test with "/usr/bin/printf '\uCODEx\n'" where 'CODE' can be
0020, 00a0, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009,
200a or 202f.
(Yes, all are different kinds of Unicode spaces. See this site if you
want more details about each char:
http://www.fileformat.info/info/unicode/char/search.htm )

Does it feel as a proper fix for you? If not, how can I improve it?

Regards,
Nicolas

ps: the script to update psf fonts is available here:
