Some of the man-pages are awful, the notorious example being the man-page of rsync(1).
Man-pages should contain more examples. They also lack hyperlinks, which can be fixed by using texinfo (preferably by using Gnu/Emacs+info mode as defined in info.el) or by reading the HTML versions if the man-pages.
Terry DAVIS said that UTF-32 should be the standard encoding.
This also reminded me of the interactive TempleOS document files (DolDoc) with spires and all: https://templeos.holyc.xyz/Wb/Doc/DolDocOverview.html
