# 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:

```rust
use u_plus::U;

assert_eq!(U+1234, '\u{1234}');
```

So forget about `\u{…}` syntax!

(Caution: there are some limitations with this approach, see KNOWN_ISSUES.md for details.)
