I would suggest devising a method capable of intersecting characters, e,g.,
https://www.lawlist.com/images/22873_17684_light_dark_backgrounds.png
Using features 17684/22873, Emacs can quickly generate up to three lines that
are capable of intersecting characters ... The current draft patch is version
021.004 [06/29/2019]:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22873#155
Using features 17684/22873, I have not run any tests to see how many vertical
lines could be drawn before there is an appreciable performance hit. The
current design only redraws what has changed since the previous redisplay, so
it may be possible to draw several vertical lines without any performance hit
at all ...
One idea that I have not tried would be to use a thin window like a scroll bar
window to draw a vertical line ...
