Allegedly, on or about 12 October 2017, Jonathan Ryshpan sent:
In the command interpreter (shell) the underline character
(underline_char) generally but not always echos as a space when
actually typed and generally but not always displays as an underline
when produced by the system. For example:
(1) $ echo underline_char
(2) underline_char
the underline echos as a space when actually typed on line (1) but
then changes to an underline when I hit return and line (2) appears.
Line (2) displays properly.
I don't see that, here.
I'm wondering if you're not using your screen at its native resolution,
and sometimes the underline is less than a pixel height and doesn't
display.

Lucky for you I typed this, you'd never be able to read my handwriting.
