### Perform Unicode Case Mapping

Source: https://github.com/yeslogic/unicode-case-mapping/blob/master/README.md

Demonstrates usage of the crate's mapping functions for lowercase, uppercase, titlecase, and case folding operations.

```rust
fn main() {
    assert_eq!(unicode_case_mapping::to_lowercase('İ'), ['i' as u32, 0x0307]);
    assert_eq!(unicode_case_mapping::to_lowercase('ß'), ['ß' as u32, 0]);
    assert_eq!(unicode_case_mapping::to_uppercase('ß'), ['S' as u32, 'S' as u32, 0]);
    assert_eq!(unicode_case_mapping::to_titlecase('ß'), ['S' as u32, 's' as u32, 0]);
    assert_eq!(unicode_case_mapping::to_titlecase('-'), [0; 3]);
    assert_eq!(unicode_case_mapping::case_folded('I'), NonZeroU32::new('i' as u32));
    assert_eq!(unicode_case_mapping::case_folded('ß'), None);
    assert_eq!(unicode_case_mapping::case_folded('ẞ'), NonZeroU32::new('ß' as u32));
}
```
