What people use Unicode Converter for

• Finding the code point of a character for an escape sequence.
• Converting text to and from Unicode escapes.
• Diagnosing a character that displays incorrectly.

Unicode Converter: limits and things worth knowing

• A code point is written U+ followed by hex, so U+0041 is 'A'. Escape syntax differs by language: \u0041 in JavaScript, \N{...} by name in Python.
• Characters above U+FFFF are stored as surrogate pairs in UTF-16, which is why JavaScript reports a length of 2 for a single emoji.
• A visible character can be several code points. An emoji with a skin tone or a country flag is a sequence joined by modifiers or zero-width joiners.
• Visually identical characters can have different code points — Cyrillic 'а' and Latin 'a' look the same and are not equal, which is the basis of homograph attacks.

Is it private and secure?

Your privacy is built in. Unicode Converter runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
