About Invisible Character Detector

Our Invisible Character Detector scans your text for hidden Unicode characters that are invisible to the naked eye but can cause serious issues in code, documents, and security contexts. Zero-width characters and control characters can be used to hide messages, break code execution, or bypass filters.
