You should install the font and check it out. 2 - what you see in screenshot is not period, 3 - backtick exists, not in that screenshot, 4 - lowercase l is curved and totally different from 1

You can go to color options in darkreader and set solarized as the theme.

Same about Luxi Mono. I have also added a dot. I used to program in old redhat linux with crt monitor. And at that time, it used to be the default font for terminals.
