Scope of the result
This is not a security scanner that determines whether every Unicode character is safe. It focuses on invisible and directional characters that often cause display or comparison problems.
Frequently asked questions
- Can I delete every invisible character?
- No. ZWJ and variation selectors are required by emoji and some writing systems. The inspector classifies them and does not remove everything indiscriminately.
- Does a bidirectional control always mean the text is dangerous?
- No. It has legitimate uses in right-to-left text, but it can also change how URLs or source code appear. Verify the source and intended use.
- Is my text uploaded?
- No. Inspection and candidate generation run entirely in your browser.
