Unicode Converter – Text, Unicode & Character Encoding

Encode text to Unicode code points or decode U+, \u, and hex notations back to readable characters.

What Is Unicode?

Unicode provides one universal character set for the world's scripts, symbols, and emoji.

Applications rarely store abstract code points directly; they store UTF-8 or UTF-16 byte sequences instead.

How to use this unicode converter tool

  1. Enter text or Unicode sequences in the input panel.
  2. Choose an output format for encoding (U+, \u, \u{}, \U, or plain hex).
  3. Click Encode to produce code points, or Decode to turn sequences into characters.
  4. Use Swap to move the result back into the input for another pass.
  5. Copy the result with one click.

How to Use This Tool

  • Encode plain text to U+ or escape notation.
  • Decode pasted Unicode sequences to readable output.
  • Swap input and result to chain conversions.
  • Toggle spacing between code points when encoding.
  • Copy results for documentation or source code.

Unicode vs ASCII

  • ASCII covers 128 characters; Unicode covers virtually all written languages.
  • ASCII is a subset of Unicode.
  • UTF-8 bridges Unicode to bytes efficiently on the web.

Unicode Code Points

  • Written U+ followed by hexadecimal (minimum four digits, more for large values).
  • Basic Multilingual Plane (BMP) — U+0000 to U+FFFF.
  • Supplementary planes — emoji and rare historic scripts.

UTF-8 Explained

  • 1 byte for ASCII-range characters.
  • 2–3 bytes for most non-Latin scripts.
  • 4 bytes for many emoji and rare characters.
  • Self-synchronizing byte patterns help parsers recover from errors.

Emoji Encoding

  • Emoji are assigned code points (e.g. U+1F600 GRINNING FACE).
  • In UTF-8, emoji typically use four bytes.
  • Use \u{1F600} or U+1F600 format when sharing escape sequences.

Unicode Examples

InputU+ notation
AU+0041
éU+00E9
HelloU+0048 U+0065 U+006C U+006C U+006F
😀U+1F600

Conversion Formula

Encoding text to Unicode code points:

  • For each character: codePoint = character.codePointAt(0) (use full code point for surrogate pairs).
  • Display as U+ plus uppercase hex, zero-padded to at least four digits.
  • UTF-8 byte length is separate from code point value — see Text to Binary for bit patterns.

Multilingual Text Support

  • Arabic, Devanagari, Han characters, Cyrillic, and more share one standard.
  • Normalization (NFC/NFD) can change combining sequences — be aware when comparing strings.
  • Pair with ASCII Converter for legacy 7-bit English-only data.

unicode converter — frequently asked questions

Unicode is a standard that assigns a unique code point to virtually every character in every language, plus symbols and emoji.

Enter text and click Encode. You will see values like U+0048 for "H" or \u{1F600} for emoji when that format is selected.

Paste U+ sequences, \u escapes, or hex and click Decode to rebuild the original string.

A numeric ID for a character in the Unicode standard, written as U+ followed by hex (e.g. U+1F600 for 😀).

UTF-8 is the common encoding that stores Unicode code points as one to four bytes. It is used on the web and in most modern files.

Many emoji have code points above U+FFFF, so UTF-8 uses four bytes for those characters.

\uXXXX uses four hex digits (BMP). \u{...} can use variable length for emoji and supplementary characters.
