Unicode Encoding and Decoding

Unicode escape sequences are used to represent characters that might not be easily typeable or that could cause issues in certain file encodings. In JavaScript, these typically take the form `\uXXXX` where `XXXX` is the hexadecimal code point. In CSS, the backslash followed by hex is used, and in HTML, decimal or hex entities are standard. Examples include &#xXXXX; or &#XXXX;.

When to use Unicode Escapes?

Developers often use Unicode escapes when writing internationalized applications. For example, instead of including special characters directly in a `.js` file, which might break if the file is served with the wrong charset, you can use `\u00A9` for the copyright symbol. This ensures the character is always interpreted correctly.

Support for Multiple Formats

Our tool supports the most common development formats:

  • JavaScript: Uses the standard `\uXXXX` format for string literals.
  • CSS: Uses the `\XXXX` format, commonly used in the `content` property of pseudo-elements.
  • HTML: Uses hexadecimal entities like &#xXXXX;, perfect for safe inclusion in markup.

Frequently Asked Questions

Unicode encoding is a way to represent non-ASCII characters (like emojis or special symbols) using escape sequences. This ensures that the characters are transmitted correctly across different systems and programming languages.
You should use them when your source file encoding might not be UTF-8, or when you want to ensure that specific characters are not accidentally modified by text editors or minifiers.
Switch the tool to "Decode" mode and paste your escaped strings (e.g., \u0048\u0065\u006c\u006c\u006f). The tool will instantly convert them back to readable text.
