Function icu::properties::sets::load_deprecated

pub fn load_deprecated(
    provider: &impl DataProvider<DeprecatedV1Marker>
) -> Result<CodePointSetData, PropertiesError>

Deprecated characters. No characters will ever be removed from the standard, but the usage of deprecated characters is strongly discouraged.

Example

use icu_properties::sets;

let data =
    sets::load_deprecated(&icu_testdata::unstable())
        .expect("The data should be valid");
let deprecated = data.as_borrowed();

assert!(deprecated.contains('ឣ'));  // U+17A3 KHMER INDEPENDENT VOWEL QAQ
assert!(!deprecated.contains('A'));
