homoglyph-detect

Detect Cyrillic / Greek / fullwidth lookalike chars masquerading as ASCII letters. Catches the cl\u{0430}ude trick that bypasses keyword matching.

use homoglyph_detect::{find_homoglyphs, normalize_to_ascii};
let attack = "cl\u{0430}ude";
let hits = find_homoglyphs(attack);
assert_eq!(hits[0].ascii_equivalent, 'a');
assert_eq!(normalize_to_ascii(attack), "claude");
