That's a very narrow view of the world. One example: In the past I have handled bilingual english-arabic files with switches within the same line and Arabic is written from left to right.
There are also languages that are written from to to bottom.
Unicode is not exclusively for coding, to the contrary, pretty sure it's only a small fraction of how Unicode is used.

They didn't need computers either so "was seemingly not needed in the past" is not a good argument.
Yes, it is. Unicode has undergone major mission creep, thinking it is now a font language and a formatting language. Naturally, this has lead to making it a vector for malicious actors. (The direction reversing thing has been used to insert malicious text that isn't visible to the reader.)
> Unicode is not exclusively for coding
I never mentioned coding.
> They didn't need computers
Unicode is for characters, not formatting. Formatting is what HTML is for, and many other formatting standards. Neither is it for meaning.
The fact is that there were so many character sets in use before Unicode because all these things were needed or at least wanted by a lot of people. Here's a great blog post by Nikita Prokopov about it: https://tonsky.me/blog/unicode/

But not one that would surprise anyone familiar with WalterBright's antics on this website…
At least my antics do not include insulting people.

Sometimes you gotta say no. Trying to please every hare brained idea leads to madness.
Normalized code point sequences are another WTF feature.
Unicode is for human beings, not machines.
How does invisible Unicode text fit into that?
It's not text, it's control characters, which have always been in character sets going back to ASCII.
ASCII having a few obsolete control characters does not justify opening the floodgates.
