A QUICK WALKTHROUGH
How to use this tool
- Enter text to inspect.
- Review each code point, known name, and visible escape.
- Use the position and code point to investigate further.
Bundled names only
Names are provided for a limited map of common whitespace, control, and format characters. Other code points are labeled unknown rather than guessed.
Safe local inspection
Input is limited to 10,000 Unicode characters and is rendered as text. No text is uploaded.
Visible escapes
Each code point is shown as U+ notation plus a JSON-style escaped character representation.
