```rust
extern crate unicode_segmentation;

use unicode_segmentation::UnicodeSegmentation;

fn main() {
    let s = "a̐éö̲\r\n";
    let g = UnicodeSegmentation::graphemes(s, true).collect::<Vec<&str>>();
    let b: &[_] = &["a̐", "é", "ö̲", "\r\n"];
    assert_eq!(g, b);

    let s = "The quick (\"brown\") fox can't jump 32.3 feet, right?";
    let w = s.unicode_words().collect::<Vec<&str>>();
    let b: &[_] = &["The", "quick", "brown", "fox", "can't", "jump", "32.3", "feet", "right"];
