Agreed.  But industry, to my recollection and Googling, seems to have
settled on symmetric quotes that could double as accents to get the most
use out of those two bytes.  The lineprinter we had, don't know the make
other than it wasn't IBM nor DEC, also made them symmetric.

It's not the displays that matter.  Those seeing asymmetric `' that
would like that changed have displays that can, and normally do, render
with -Tutf8 and so see symmetric ‘’ instead.  It's if they choose, or
are coerced, into a LC_CTYPE=C locale causing -Tascii that they see
asymmetric `'.

Cheers, Ralph.
