§Example
use icu::properties::CodePointSetData;
use icu::properties::props::XidStart;
let xid_start = CodePointSetData::new::<XidStart>();
assert!(xid_start.contains('x'));
assert!(!xid_start.contains('1'));
assert!(!xid_start.contains('_'));
assert!(xid_start.contains('ߝ')); // U+07DD NKO LETTER FA
assert!(!xid_start.contains('ⓧ')); // U+24E7 CIRCLED LATIN SMALL LETTER X
assert!(!xid_start.contains('\u{FC5E}')); // ARABIC LIGATURE SHADDA WITH DAMMATAN ISOLATED FORM
