husher

A library to analyze text that contains special unicode characters that are unnoticeable by naked eye but are interpretable by LLMs.

Features:

1. ⭐️ hush - encode input string into hidden text with zero-width characters
2. ⭐️ dehush - reverse the process and discover the hidden text
3. ⭐️ sanitize - sanitize the text from hidden text characters
4. Support dehush of flag emojis, utf-8 and other multilingual charsets, while the hidden characters are type of flag emoji with custom payload.

example input: "clear text, flag: 🇨🇦, utf-8: א, hushed payload: 󠁳󠁨󠁨󠁨󠀡" ->
example output: "clear text, flag: 🇨🇦, utf-8: א, hushed payload: shhh!"
