What does this tool do?
The Unicode Converter turns text into \uXXXX-style Unicode escape sequences and converts those sequences back into readable text. It's useful for developers, translators, and content creators working with multilingual characters, emoji, or special symbols.
How to use it
- Enter the text you want to encode or decode.
- The conversion happens automatically.
- Copy the result and use it safely.
How encoding and decoding work
In encode mode the tool converts every character above the ASCII range (code point 127) into a \u escape sequence of at least four hexadecimal digits, while plain ASCII characters are left untouched. In decode mode it finds \uXXXX sequences and turns them back into the actual character they represent. This lets you safely carry accented letters, emoji, and other symbols through source code, JSON files, and configuration without garbling them along the way.
Character breakdown and code points
While encoding, the tool shows a breakdown of the first characters in your input: each one is listed with its official Unicode code point in U+XXXX form. That makes it easy to see exactly which code point an emoji or accented letter maps to, which is handy for debugging or for documenting reference values. Characters outside the basic plane, such as many emoji, are resolved to their correct code points too.
Frequently asked questions
Why are ASCII characters left unchanged?
The tool only escapes characters above code point 127, so standard English letters and symbols stay readable instead of being needlessly escaped.
Can I encode emoji and decode them back?
Yes. Emoji are encoded to their correct code points, and decode mode turns the same sequences back into the original emoji.
Which escape format does it use?
It uses the \uXXXX hexadecimal format that works in JavaScript, JSON, and many languages; decoding recognizes four- to six-digit hex values.
