7//!
8//! // U+0307 is COMBINING DOT ABOVE
9//! assert_eq!(unicode_case_mapping::to_lowercase('İ'), ['i' as u32, 0x0307]);
10//! assert_eq!(unicode_case_mapping::to_lowercase('ß'), [0; 2]);
11//! assert_eq!(unicode_case_mapping::to_uppercase('ß'), ['S' as u32, 'S' as u32, 0]);
12//! assert_eq!(unicode_case_mapping::to_titlecase('ß'), ['S' as u32, 's' as u32, 0]);
13//! assert_eq!(unicode_case_mapping::to_titlecase('-'), [0; 3]);
14//! assert_eq!(unicode_case_mapping::case_folded('I'), NonZeroU32::new('i' as u32));
15//! assert_eq!(unicode_case_mapping::case_folded('ß'), None);
16//! assert_eq!(unicode_case_mapping::case_folded('ẞ'), NonZeroU32::new('ß' as u32));
