Crate moine_ja 

Japanese kana, romaji, override, and UniDic adapters for moine.

This crate converts Japanese surface text into romaji lattices through direct kana/ASCII handling, manual override dictionaries, or UniDic-derived reading artifacts. The language-independent edit-distance algorithms remain in moine-core.

Dictionary artifacts are external input. Prefer try_* lookup and expansion APIs at trust boundaries so indexed-payload decode errors are reported as UnidicArtifactPayloadError instead of being collapsed into empty lookup results for backward-compatible convenience APIs.

use moine_ja::romaji_lattice;
use moine_core::{distance, Lattice};

let left = romaji_lattice("もいにゃ").unwrap();
let right = Lattice::from_paths(["moinya"]);

assert_eq!(distance(&left, &right), 0);
