Look, I have looked up what those characters mean every time these comments come up, but no one else cares or uses them. Including me. So I forget what they are, because it's not important to me. Then it comes up again in a comment on here and nowhere else and I just can't be fucked to bother looking it up again. So I don't read those comments anymore.

I'm not mad, or stupid. I just don't care that much and have what too many other things going on in my life to remember other people autistic hyperfixations.

This is likely the most common way people intereract with your comments. So if you want to turn every interaction into either a fight over those characters or only have it read by other etymology autists then sure, Have at it. I, however, want to be understood when I talk. It bothers me when people don't understand me. To me the point of language is to get ideas across through any means necessary. By that standard I really don't see the point in putting any effort to bringing these characters back. They do not help language to be better understood or clearer and that's all I care about.

And in my experience, trying to force changes like that through use will just get tiring and not actually change anyone else. This kind of change in language would take tremendous effort. Even if I thought there was a point to it, I would call it a pipe dream to make it standard.
