Unicode Text Converter & Decoder

• Converts any text character to its Unicode code point in U+XXXX format (BMP) or U+XXXXX format (supplementary planes)
• Decodes multiple escape formats: U+ notation, JavaScript/Python \u escapes, HTML &#x entities, and 0x hex values
• Supports all Unicode 15.1 characters: Latin, CJK, Arabic, Cyrillic, Devanagari, emoji, mathematical symbols, and 161 scripts
• Handles supplementary plane characters (emoji, rare CJK, musical notation) that use surrogate pairs in UTF-16
• Essential for debugging encoding issues, internationalization (i18n), and localization (l10n) in multilingual applications

Use Cases

Frequently Asked Questions

How do I convert text to Unicode code points (U+XXXX format)?

Enter or paste any text in the encode panel. The converter displays each character's Unicode code point in U+XXXX format (or U+XXXXX for supplementary plane characters). For example, 'Hello' produces U+0048 U+0065 U+006C U+006C U+006F. This works for all languages, emoji, special symbols, and mathematical characters across all 17 Unicode planes.

What Unicode escape formats can I decode with this tool?

The decoder accepts multiple Unicode notation formats: U+ prefix (U+0041), JavaScript/Java \u escapes (\u0041), Python \U long form (\U00000041), HTML numeric character references in hex (A) and decimal (A), and bare hexadecimal with 0x prefix (0x41). You can mix formats in a single input — the tool parses each code point individually regardless of notation style.

Can I convert emoji to Unicode code points and find their hex values?

Yes. Paste any emoji into the encode panel to see its Unicode code point(s). Simple emoji have single code points (grinning face = U+1F600), while complex emoji are multi-codepoint sequences. For example, a family emoji may consist of person + ZWJ (U+200D) + person + ZWJ + child code points joined together. The converter shows every component code point in the sequence.

How does this Unicode converter help debug encoding issues and mojibake?

Mojibake (garbled text) occurs when text is decoded with the wrong character encoding. By converting both the garbled output and the expected text to Unicode code points, you can compare them character by character to identify where the mismatch occurs. For example, if 'e' (U+00E9) appears as 'é', the code points reveal it was UTF-8 bytes (C3 A9) interpreted as Latin-1 characters (U+00C3 U+00A9).

Does the converter support CJK characters, Arabic, Cyrillic, and other non-Latin scripts?

Yes. The converter supports all 161 scripts in Unicode 15.1, including CJK Unified Ideographs (Chinese, Japanese Kanji, Korean Hanja), Hiragana, Katakana, Hangul, Arabic, Hebrew, Cyrillic, Greek, Devanagari, Tamil, Thai, Georgian, Armenian, and every other Unicode-encoded script. Supplementary CJK characters (Extension B through Extension I) on higher Unicode planes are also fully supported.

Is my text data sent to a server when using this Unicode converter?

No. All Unicode encoding and decoding is performed entirely in your browser using client-side JavaScript. Your text — whether it contains personal information, multilingual content, or proprietary data — is processed in memory on your device and never transmitted over any network. The tool works even when offline after the initial page load.

What is the difference between UTF-8, UTF-16, and Unicode code points?

Unicode code points (U+XXXX) are abstract numeric identifiers for characters. UTF-8 and UTF-16 are encoding schemes that represent these code points as byte sequences. UTF-8 uses 1-4 bytes per character (backward compatible with ASCII), while UTF-16 uses 2 or 4 bytes (with surrogate pairs for supplementary characters). This converter works with Unicode code points directly, which are encoding-independent — you can then use the code points to generate the appropriate escape format for your target encoding or programming language.
