1.23: UTF-8 device: more display oddities

[Steffen Nurpmeso]

Hello.

Letting aside the hyphen-minus -> hyphen thing that i fixed for me
locally, there is also the problem that

  ` U+0060, GRAVE ACCENT, "backtick"

is displayed as

  ‘ U+2018, LEFT SINGLE QUOTATION MARK

which in Liberation Mono (at least!) this reverses the direction
of the tick.

I was looking at a manual which uses backtick syntax notation for
sh(1)ell commands (aka i=`echo one`, not new-style i=$(echo one)),
and it _really_ looks strange.

Could be done something about this, please?
Thank you.
