About this tool
About this tool
Invisible Character Detector scans text for zero width, non-breaking spaces, and other hidden Unicode code points by analyzing characters inside your browser. Detected positions are highlighted for removal.
Find zero-width and other invisible Unicode characters. Use the full-width workspace to process content while reviewing lines, words, characters, whitespace, and Unicode content. The tool accepts plain text, provides focused options, and creates plain text output that you can inspect, copy, download, or save as a local draft.
Built for daily work
- Use Invisible Character Detector for editing, publishing, data preparation, and everyday text cleanup.
- Apply the selected operation and produce a reviewable result before content is imported, published, committed, shared, or passed to another application.
- Check a small sample interactively before applying the same operation to a larger plain text workflow.
- Prepare cleaner plain text output for teammates, clients, documentation, testing, or downstream automation.

Key features
Key features
Reveal hidden characters in text
Scan your text for non-printing characters such as zero-width spaces, non-breaking spaces, soft hyphens, left-to-right marks, and control characters that are invisible in normal editors.
Character type identification
Each detected invisible character is labeled with its Unicode name and code point, for example "ZERO WIDTH SPACE (U+200B)", so you know exactly what is present.
Position and line location
The tool reports where each invisible character appears by line number and column position, making it possible to locate and remove them precisely.
One-click removal option
After identifying the hidden characters, you can strip all of them from the text in a single step and download or copy the cleaned result.
