Zero-width steganography utilities for invisibly embedding data in text using Unicode zero-width characters

/**
 * Zero-Width Steganography Utils
 * Invisible data embedding using zero-width Unicode characters.
 *
 * Embed arbitrary BMP-range string data into visible text using zero-width
 * Unicode characters. The embedded data is invisible to humans but trivially
 * recoverable programmatically.
