About Unicode Inspector

The Unicode Inspector is a web application that displays detailed Unicode information for each character in your input text in real time. It shows UTF-8/UTF-16 byte sequences, Unicode block names, general character categories, and escape formats for JavaScript, HTML, CSS, and Python.

It helps developers investigate character encoding, debug internationalization (i18n) issues, and detect invisible characters such as zero-width spaces, BOM markers, control characters, and soft hyphens. The tool also displays Unicode Normalization information (NFC/NFD), allowing you to visually compare composed and decomposed character forms.

The code point search feature lets you enter a code point in U+XXXX, hexadecimal, or decimal format to instantly find the corresponding character. All processing happens entirely in your browser with no data sent to any server. This tool is invaluable for developers, technical writers, linguists, and anyone investigating text encoding issues.

How to use Unicode Inspector

  1. Paste or type the text you want to inspect into the input textarea. Supports multiple languages, emoji, and control characters.
  2. A detailed table instantly displays each character's code point (U+XXXX), UTF-8/UTF-16 bytes, Unicode block name, and category.
  3. Invisible characters (zero-width spaces, BOM, control chars) are highlighted in red for easy detection.
  4. Enter a code point (U+XXXX, 0xXX, or decimal) in the search field to instantly look up any Unicode character.
  5. The normalization info panel displays NFC (composed) and NFD (decomposed) forms, showing how text is canonically normalized.
  6. Copy escape formats (JavaScript, HTML, CSS, Python) directly into your code without manual conversion.

Benefits of Unicode Inspector
