use somen::prelude::*;

let mut parser = utf32();
let mut stream = stream::from_slice(&[0x41, 0xC5, 0x3042, 0x1F4AF, 0x110000]);

assert_eq!(parser.parse(&mut stream).await, Ok('A'));
assert_eq!(parser.parse(&mut stream).await, Ok('Å'));
assert_eq!(parser.parse(&mut stream).await, Ok('あ'));
assert_eq!(parser.parse(&mut stream).await, Ok('💯'));
assert!(parser.parse(&mut stream).await.is_err());
