Unicode Converter

Convert between Unicode and characters

Use Unicode Converter

Load a Unicode debugging sample
If the output is headed into HTML, verify entity escaping with the HTML Entity Encoder. For URL-bound Unicode text, use the URL Encoder/Decoder, then count or normalize the final string in the String Length Counter.

Examples:

A→U+0041
€→U+20AC
中→U+4E2D
😀→U+1F600

Assumptions

Use Unicode Converter for encoding and auth debugging work when you need a local browser check and output you can review before using it in the next step.

Worked example

When To Use Unicode Converter

  • Paste a real example into Unicode Converter that includes the edge case you need to check.
  • Review whether the output matches inspect transformed strings before they move into requests or templates before using it in the next step.

Sample Input And Output Checks

  • Start with a sample that includes the failure you are trying to reproduce, not only a clean placeholder.
  • Review padding, escaping boundaries, token segments, and copied delimiters before trusting the output.
  • Treat decoded or escaped output as readable input for the next step, not as automatically trusted data.

About This Tool

Unicode is a universal character encoding standard that assigns a unique code point to every character in every language. This converter helps you convert between characters and their Unicode representations in various formats.

What is Unicode?

Unicode is a computing industry standard for consistent encoding, representation, and handling of text expressed in most of the world's writing systems. It contains over 143,000 characters covering 154 modern and historic scripts, as well as emoji, symbols, and mathematical notation. Each character is assigned a unique code point, typically written as U+XXXX in hexadecimal.

Unicode Formats

  • U+ Format: Standard Unicode notation (U+0041 for 'A')
  • Hex Format: JavaScript/JSON escape sequence (\u0041)
  • Decimal Format: HTML numeric entity (A)
  • Hex HTML: HTML hex entity (A)

Common Use Cases

Unicode conversion is essential for web development when handling international characters, displaying special symbols and emoji, debugging character encoding issues, working with escape sequences in programming, and ensuring cross-platform text compatibility. For converting text case while preserving Unicode characters, use our Case Converter tool.

UTF-8 vs UTF-16

While Unicode defines code points, UTF-8 and UTF-16 are encoding schemes that determine how those code points are stored in bytes. UTF-8 uses 1-4 bytes per character and is backward compatible with ASCII, making it the most popular encoding for the web. UTF-16 uses 2 or 4 bytes and is used internally by JavaScript and many operating systems.

Emoji and Special Characters

Modern Unicode includes thousands of emoji and special characters. Emoji typically use code points above U+1F000 and may consist of multiple code points combined (like skin tone modifiers or combined emoji). This converter handles all Unicode planes, including the Supplementary Multilingual Plane where emoji reside, supporting characters from U+0000 to U+10FFFF.

Debugging Broken Characters

When text renders as boxes, question marks, or escaped sequences in an API response, convert one small sample first and compare the code points against the source system. If the output needs to appear in markup, check it with the HTML Entity Encoder. If it needs to travel inside a query string, run the converted text through the URL Encoder/Decoder so percent encoding does not corrupt non-ASCII characters.

When No Unicode References Match

A no-match result means the input is likely already plain text or uses a notation this page should not transform automatically. Review whether the source contains JavaScript escapes, HTML numeric entities, or plain UTF-8 text before replacing production content.
