About Unicode Converter

A Unicode converter helps when text arrives as codes instead of characters: a JSON response full of \u4e2d\u6587, a Java properties file, a URL or log with %E4%B8%AD in it, or an emoji you need to write into source code. Paste the codes and the converter works out the format on its own, whether they're \u escapes, &# codes, U+ code points or UTF-8 bytes.

Encoding goes the other way. You can write text as \uXXXX escapes, where emoji and other characters above U+FFFF become surrogate pairs or \u{…}, as decimal or hex HTML codes, as U+ code points, as UTF-8 bytes in hex or %XX form, or as UTF-16. A table lists every character with its code point and UTF-8 bytes, which makes a stray zero-width space or a look-alike letter easy to find. It all runs in your browser.

How to use Unicode Converter

    Plain text to encode, or escapes, codes or bytes to decode.

  2. 2
    Pick the output format

    Choose \uXXXX, decimal or hex HTML codes, U+ code points, UTF-8 bytes or UTF-16.

  3. 3
    Check the table

    Each character is listed with its code point and UTF-8 bytes.

  4. 4
    Copy the result

    Copy the converted text or codes.

Why use Cubfile for this

  • Format detected for you

    Paste \u escapes, &# codes, U+ points or UTF-8 bytes and they're decoded without choosing a mode.

  • Emoji handled properly

    Characters above U+FFFF become surrogate pairs or \u{…}, so nothing is lost on the way back.

  • UTF-8 and UTF-16 bytes

    See UTF-8 bytes as hex or as %XX, the form used in URLs.

  • Character table

    Code point and UTF-8 bytes for every character in the text.

FAQ

Unicode Converter: questions and answers

How do I convert \u escapes to readable text?
Paste the string, for example \u4f60\u597d, and it decodes to 你好. The format is detected automatically, so &#…; codes and U+ code points work the same way. Named HTML entities such as © or   are decoded by the HTML Entity Encoder/Decoder.
Why is one emoji written as two \u codes?
A \uXXXX escape holds four hex digits, enough for U+0000 to U+FFFF. Emoji sit above that range, so JSON and JavaScript write them as a surrogate pair, such as \uD83D\uDE00 for 😀. Newer JavaScript also accepts \u{1F600}.
What's the difference between a code point and UTF-8 bytes?
The code point is the character's number in Unicode, like U+4E2D for 中. UTF-8 is how that number is stored, here as three bytes, E4 B8 AD, which is also what %E4%B8%AD in a URL means. For the same text as GBK or UTF-16 bytes, use the Text to Hex Converter.
How do I find the Unicode code point of a character?
Paste the character and read the table. Each one is listed with its U+ code point and its UTF-8 bytes, including invisible characters you can't see on screen.
Is my text uploaded when I use the Unicode converter?
No. The conversion runs in your browser, keeps working offline once the page is open, and has no daily limit.
