I would think something like this:

      |
      |  \
      |   \
      |    \  /\
      |     \/  \
      |          \
      |          _\/
      |
      +———————————————
Could (more or less) fit that description and would make more sense as a symbol. Something like it even made it into Unicode (https://emojipedia.org/chart-decreasing/)

Sometimes people should be able to do nice things without it getting abused, no? In The Netherlands, in the nicer neighborhoods we have something called a ‘buurtbieb’ aka a ‘neighborhood libraries’, which is a weatherproof cabinet where people can put surplus books that other people in the neighborhood can borrow. Of course you could take all the books or use the cabinet to store candy, but why would you?

Usually called Little Free Libraries in the US. (The name is a little weird, because regular libraries are also free...)

Obligatory "Free as in beer vs. free as in freedom" comment. I have pulled stuff out of small community bookshelves that would never have seen their chance in a "professional-run" public library, both bad and good.

Unicode had to define the bidirectional rendering Why? They could have left this for a higher layer to handle.

Unicode defines characters, their semantics and (very flexible) guidelines for rendering them. Unlike, say, bold, italic or super/subscripts, bidirectionality is an intrinsic property of those characters and can't be easily refactored.

Should a universal text encoding provide a way to encode the names of mathematical and physical quantities?

In my opinion, yes. If it can't, it's not fit for purpose, no matter what is or is not an intrinsic property of some characters...

I remember back in the day we used to find publicly exposed Windows FTP servers, create new folders using some messed up unicode characters and upload pirated games and movies there to share with each other. The only way to open those directories was to specifically type the exact path in unicode, simply double clicking on the folder in filezilla or windows explorer resulted in a error. Sometimes the admins themselve…

That exact memory crossed my mind as soon as I saw that U + in the title :-D. Fun times indeed!

I generally (perhaps naively) think that going forward knowledge loss won't be much of an issue compared to our history. Surely the archeologists of the future won't have to wonder what some tool from our times was used for or what some symbol we currently use means… They will have Wikipedia and archive.org and whatnot! But that fantasy is not compatible with reality where we are already unable to find out what is th…

That presumes humans can access our (electronic) media and understand it, in some 8.000 years or further.

There's no saying that there'll be a society capable of reading bits and bytes by then. Not just collapsed society -they'll hardly be interested in reading a random discussion on an orange forum for a niche group that lived 8000 years ago- but maybe even societies that are vastly technical superior to our own but cannot fathom what things meant 8 millenia back. I mean we have texts from some 600 years ago, that we can read, but cannot understand (e.g. Rohonc Codex). Eventhough our technology and knowledge is far superior to when it was written.

Dislosure: I'm not directly from the fields of the Sciences Of Angles And Ambiguously Crossing Lines nor I've every seen or used this symbol before. However to me it's, pretty evidently, supposed to be a "no right angle" symbol.

(A) It's in the math section, (B) it's with angles, (C) the thunderbolt ↯ is commonly used for "not" or more specifically for dis-proof in this area and

(D) at least by my 30 s internet search on a mobile phone I couldn't find any other "no-angle" or "no-right-angle" symbol.

Someone could argue that usually you use a simple strike through as like as in ≠ (unequal), ∉ (not-element-of) or ∅ (empty set) but I would say it was chosen to avoid confusion in this case. The angle itself (without the "no/not") consists of only to orthogonal lines so it would be kinda complicated to "strike it though" in any direction without ambiguity that would resemble a triangle, a fork or whatnot.

The word "public" in "public library" is load bearing, you can't replace it with "regular", hence your confusion.

Private libraries (mine for example) are not free, as in beer or otherwise.

On the contrary: books might survive total societal collapse, but electronics don't.
