npm install --save @nahanil/zh-decomp

const decomp = require('@nahanil/zh-decomp')

lookup(char)

let res = decomp.lookup('蟆');
/*

radical(char)

This will likely be removed in future in favour of @nahanil/bushou

decomp.radical('蟆')
// '虫' <-- Found radical

decomp.radical('虫')
// '*' <-- 虫 is a radical

decomp.radical('U')
// null <-- 'U' not found
