Whitespace can be intentional. A match is a technical observation, not evidence of malicious content.

How it works

Invisible Character Detector is designed to give you the result immediately. The calculation or processing happens on your device for this tool, so normal use does not require an account or a file upload.

Privacy

This tool is marked offline-capable. Your inputs are used in the current browser/app session and are not required to be sent to Wiunix Tools to perform the operation.

Find zero-width and Unicode formatting characters

Detect tracked zero-width characters, unusual spacing, bidi controls, formatting marks and variation selectors with their string position and code point.

A match is only a technical observation: many invisible or formatting characters are legitimate in multilingual text and emoji sequences.
