U+: pretty Unicode code point literals
I was reading https://uncyclopedia.com/wiki/Rust_(programming_language)
for some reason, and read let U = 0; U = U + 1;.
Suddenly my mind was awhirl with a Concept. I implemented it at once.
The problem
Unicode expresses its code points in syntax like U+1234 (full range U+0000–U+10FFFF).
But then when you want to transfer it to a programming language,
you have to learn another syntax. Will it be \u1234, \u{1234},
\x1E\x88\xB4, \341\210\264, something else?
And then astral plane characters make it even worse:
\U0001F631, \u{1F631}, \xF0\x9F\x98\xB1, \uD83D\uDE31
(with all the associated pain the abomination UTF-16 entails,
especially that your char type may simply not be able to represent this),
something else?
And so here is this crate that lets you use the True Unicode Syntax:
use U;
assert_eq!;
So forget about \u{…} syntax!
(Caution: there are some limitations with this approach, see KNOWN_ISSUES.md for details.)
