Unicode & BiDi Security Scanner
Inspect identifiers, domains, filenames, source code, and multilingual text for invisible format characters, bidirectional controls, mixed writing systems, and common cross-script confusables. See every code point and its exact position without uploading the text.

01
How to use
- Paste an identifier, domain, filename, source-code fragment, or multilingual string.
- Review the overall risk summary, then inspect flagged code points and their UTF-16 positions.
- Confirm every invisible, bidirectional, mixed-script, or visually confusable character with the text's author.
02
Understanding the output
The scanner identifies Unicode controls, invisible format characters, common cross-script look-alikes, and mixed scripts. Character positions use JavaScript UTF-16 indexing so they map directly to browser and editor APIs.

Common issues & tips
- β’Arabic and Hebrew text legitimately uses right-to-left rendering; a warning is a review prompt, not proof of malicious content.
- β’The confusable mapping is deliberately focused and cannot replace the complete Unicode confusables data or a language-aware identifier policy.
Frequently asked questions
- Does a BiDi warning mean Arabic or Hebrew text is malicious?
- No. Right-to-left text is legitimate. The scanner highlights explicit formatting controls and mixed-script patterns so a reviewer can confirm whether they are expected in that context.
- Can this detect every Unicode look-alike?
- No. It detects high-risk controls and a focused mapping of common confusables. Apply a complete UTS #39 implementation and a product-specific identifier policy for security-critical registration systems.
- Is the inspected text uploaded?
- No. Code-point inspection and risk classification run entirely in your browser.
