 |Oh merde, after 45 MB download IBMPlexMono has the same problem!!!

P.S.: with the help from people of IRC i have now tested LuxiMono,
IBMPlexMono, and NotoMono, and only LuxiMono gets it somehow right
(but looks terrible as a monospace font imho).

(P.P.S.: IBMPlexMono is really a great typewriter font, but must be
relatively large to look ok, only 51 lines on the screen here,
whereas Liberation and Noto are ok with 59.  Noto i find a bit
"too crouched", but the guy speaks quite some languages, including
several Asian ones, and says it offers good support for those.
I unfortunately cannot testify, too dumb a western.  Anyhow,
i have to stay with Liberation it seems, i will make an alias to
go for -Tascii, and prepare to somehow direct people to go for
-Tascii or LC_ALL=C man.  If at least literal code blocks and such
would remain unmapped.)
