Function fold_case 

pub fn fold_case(text: &str) -> String

Lowercases text using Unicode case folding semantics.

This is stricter than ASCII-only lowercasing, so it is safe to use for case-insensitive matching on user-facing text.

Examples

use osp_cli::core::fuzzy::fold_case;

assert_eq!(fold_case("LDAP"), "ldap");
assert_eq!(fold_case("ÅSE"), "åse");
