I still don't understand why Unicode has all these obscure symbols but they still haven't added all superscript/subscript numbers and letters

To quote a reply from the above StackOverflow thread: "So, they added a snowman with snow AND a snowman without snow , so that the weather forecaster of this world can avoid the dull snowflake , but we will never get our missing superscript q‽"

Someone show him U+29B0 REVERSED EMPTY SET.

Seems like Wikipedia has the answer:

> When writing in languages such as Danish and Norwegian, where the empty set character may be confused with the alphabetic letter Ø (as when using the symbol in linguistics), the Unicode character U+29B0 REVERSED EMPTY SET ⦰ may be used instead

These unicode characters feel like they were given to us from an alien species or something.

How did it we end up with so many characters of unknown origin?

I had no idea what it meant or was used for, thus assigned it a “descriptive name” when collating the symbols for the STIX project. (I still have no idea, nor can supply an example of the symbol in use.) […] it is the case that ISO 9573-13 existed long before either AFII or the STIX project were formed. […] I once asked Charles Goldfarb what the source of these entities was, but remember that he didn’t have a definitive answer.

Earlier quoted context omitted.

Clearly useful for typesetting reflections of mathematical proofs. /s

It's how Leonardo Da Vinci would type up proofs.

I think he would have typed things left to right. He only wrote in mirror because it was more ergonomic for him, but there's no such issue with a keyboard.

I don't understand, why Unicode must (should?) contain superscript and subscript glyphes at all. Declared goal of Unicode is to have encoding of all characters used by all languages, past and modern. Subscript and superscript are not used by any language as separate characters, it is typesetting property. It should be solved by other means, not by character/glyph encoding. Should Unicode include ALL characters strike-out? Underlined? Double-underlined? Small-caps variant for all letters for languages where small-caps are used in typography tradition?

And, BTW, what do you mean by "all letters"? Should Unicode contain sub/superscript variants of Hangul or Devanagari or letters from hundreds other non-latin-alphabae languages? So, Unicode must be approximately tripled, bar hieroglyphic part (and why hieroglyphics should not be sub/superscripted?)?

The name itself sounds like it should be a graph of a downward trend line on a graph.

I’m guessing the person who implemented it got this exact requirement wording in the Unicode definition and nothing else, didn’t make the logical connection, and just implemented it as close to literally as they could.
