Quick Tool Overview

The Unicode Code Point Lookup breaks any text into characters and reports the code point, block, category, UTF-8 and UTF-16 bytes and every escape form — which is how you identify an invisible character that has got into a file.

About the Unicode Code Point Lookup

Paste any text and every character is broken out with everything you might need to identify or escape it: the U+ code point in hex and decimal, the Unicode block it belongs to, its general category, and its exact bytes in UTF-8 and UTF-16.

It also gives the escape forms, which is usually the actual job. The HTML entity in decimal and hex, the CSS escape for a content property, the JavaScript escape including the brace form that astral characters need, and the percent-encoded bytes for a URL. It is the fastest way to identify an invisible character that has got into a file — a non-breaking space, a zero-width joiner, a byte order mark or a curly quote that should have been straight.

Key features of the Unicode Code Point Lookup

Invisible characters exposed

A non-breaking space, a zero-width joiner, a BOM or a curly quote is listed by name and code point instead of looking like nothing.

Bytes in both encodings

UTF-8 and UTF-16 representations side by side, which is what explains why a string length differs between languages.

Every escape form

HTML decimal and hex entities, the CSS escape, the JavaScript escape including the brace form, and percent-encoding.

Block and category

Which Unicode block a character belongs to and what kind of character it is, from the real Unicode properties.

Surrogate pairs flagged

Characters above U+FFFF are marked, because that is why an emoji has a JavaScript length of 2.

How to use the Unicode Code Point Lookup

  1. 1

    Paste any text

    One character or a whole string; every character is listed.

  2. 2

    Read the breakdown

    Code point, block, category and byte representations for each.

  3. 3

    Take an escape form

    HTML, CSS, JavaScript and URL escapes are given for every character.

  4. 4

    Find the invisible one

    Non-breaking spaces, zero-width characters and BOMs all show up by name.

Frequently asked questions

Paste the text here. Every character is listed with its code point and block, so a non-breaking space (U+00A0), a zero-width space (U+200B) or a BOM (U+FEFF) is immediately visible.
