Convert data to an unseen zero-width binary string.
import Unseen from 'unseen-data'
const unseen = new Unseen({ compression: true })
const encoded = unseen.encode('Hello world!')
// encoded = ''
const decoded = unseen.decode(encoded)
// decoded = 'Hello world!'
Options can be passed as an object in the constructor.
By default, data is compressed with pako to reduce the length of the resulting strings.
By default, unseen-data
uses a Base4 charset consisting of four different types of invisible characters.
