Remove hidden characters and watermarks from AI generated Text

I created a simple way of removing hidden characters and watermarks from AI-generated content. It’s also available as a JavaScript library, too: https://github.com/BeMoreDifferent/ai-text-sanitizer

As I’m using AI for mostly everything and also using it for spelling correction, I don’t want to have my content flagged as AI-generated. This is especially valuable in University settings as the consequences of AI content is increasing rapidly. I would be happy to get feedback and also commits if you see any missing parts or potential improvements. Feel free to add tests or make commits to cover further cases (but I believe I covered most cases right now).
