escape8259 performs RFC8259-compliant string escaping and un-escaping.

[RFC8259] is a JSON encoding standard. Many JSON encoders exist, but other RFCs use the same string escaping mechanism, so it's useful to be able to access the string escaping functions by themselves.

Examples

```rust use escape8259::{escape, unescape};

assert_eq!(unescape(r#"\u0041\n"#).unwrap(), "A\n");

let multiline = r#"hello world"#; assert_eq!(escape(multiline), r#"hello\n world"#); ```
