Unicode is the universal character encoding standard that assigns a unique number — called a code point — to every character in every writing system in the world, plus emoji, symbols, and technical characters. The Unicode standard covers over 149,000 characters across 161 scripts. Code points are written as U+ followed by a hexadecimal number: the letter A is U+0041, the emoji 😀 is U+1F600, and the Chinese character 中 is U+4E2D.

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

Unicode is the character set standard — the list of characters and their code point numbers. UTF-8 and UTF-16 are encoding schemes — ways of representing Unicode code points as bytes in memory or files. UTF-8 uses 1-4 bytes per character (1 byte for ASCII, up to 4 for rare characters) and is the dominant encoding on the web. UTF-16 uses 2-4 bytes per character and is used internally by JavaScript, Java, and Windows. The code point U+0048 is the same character (H) in both — the encoding scheme only affects how it is stored in bytes.

What are HTML entities?

HTML entities are ways to represent characters in HTML source code without using the character directly. Decimal entities use the format &#DDDD; (e.g. H for H). Hexadecimal entities use &#xHHHH; (e.g. H for H). Both forms are decoded by browsers to the corresponding Unicode character. They are used when the character itself might be misinterpreted by HTML parsers — for example, & must be written as & and < as < in HTML content.

What is a Unicode escape sequence?

A Unicode escape sequence is a way to represent a Unicode character in source code using only ASCII characters. JavaScript and many other languages use \uXXXX for characters in the Basic Multilingual Plane (BMP) and \u{XXXXX} for supplementary characters. CSS uses \XXXXXX. Python uses \uXXXX and \UXXXXXXXX. These sequences are especially useful for including non-ASCII characters in source code files that might not support those characters directly.

What are UTF-8 bytes?

UTF-8 bytes are the actual byte values used to represent a Unicode character when encoded in UTF-8. ASCII characters (U+0000 to U+007F) use one byte each — the byte value equals the code point. Characters above U+007F use multi-byte sequences: 2 bytes for U+0080–U+07FF, 3 bytes for U+0800–U+FFFF, and 4 bytes for U+10000–U+10FFFF. For example, the letter H (U+0048) is the single byte 0x48, but é (U+00E9) is the two bytes 0xC3 0xA9.

How do I decode Unicode escape sequences back to text?

Switch to the Decode tab using the toggle at the top of the left panel. Paste your Unicode escape sequences — in any supported format including U+XXXX, \uXXXX, &#XXXX;, or &#xXXXX; — and the tool decodes them back to readable text in real time. Multiple escape formats can be mixed in the same input.

What is the difference between BMP and supplementary characters?

The Basic Multilingual Plane (BMP) covers Unicode code points U+0000 to U+FFFF — the first 65,536 characters, including all common Latin, Cyrillic, CJK, and most other scripts. Supplementary characters are code points above U+FFFF, including many emoji, rare historical scripts, and mathematical symbols. In JavaScript/Java, supplementary characters require surrogate pairs in UTF-16 (two 16-bit code units) and must use \u{XXXXX} syntax in modern JavaScript.

Unicode Converter — Text to Unicode, Hex, HTML Entities & Escape | ToolsForTexts

Introduction to the Unicode Converter

Every character on your screen — from the letter A to the emoji 😀, from the Japanese kanji 日 to the mathematical symbol ∑ — exists in memory and on networks as a number. That number is a Unicode code point: a universally agreed-upon identifier defined by the Unicode Consortium that maps every character in every writing system on Earth to a unique integer. Understanding and working with these code points is a daily requirement for web developers, front-end engineers, localisation specialists, security researchers, and anyone who handles text in code.

This free Unicode converter converts any text to six output formats simultaneously — U+ hex notation (U+0048), HTML decimal entities (H), HTML hex entities (H), JavaScript/CSS escape sequences (\u0048), UTF-8 byte values (0x48), and raw decimal code points (72) — all in real time as you type. Switch formats with one click, copy any format directly from its card without switching the active view, and decode Unicode escape sequences back to readable text in the reverse direction. A per-character breakdown tab lets you inspect every character's code point, Unicode block, plane, and all six format representations simultaneously.

All processing runs entirely in your browser. No data is sent to any server. Supports the full Unicode range — ASCII, extended Latin, CJK characters, emoji, supplementary plane characters, and everything in between.

What This Unicode Converter Can Do

Six Output Formats Simultaneously

Convert to U+ Hex (U+0048), HTML Decimal (H), HTML Hex (H), JS/CSS Escape (\u0048), UTF-8 Bytes (0x48), and Raw Decimal (72) — all computed in parallel. Switch the active format with one click; the output updates instantly.

Per-Format Copy Buttons

Every format card in the left panel has its own Copy button. Copy U+ Hex while your active view shows JS Escape, without switching. Copy multiple formats in one session without re-entering your text.

Bidirectional — Decode Unicode to Text

Switch to Unicode → Text mode to decode escape sequences back to readable characters. Supports mixed-format input: U+XXXX, \uXXXX, \u{XXXXX}, &#XXXX;, &#xXXXX;, and 0xHH hex bytes — all in the same input, decoded simultaneously.

Character Breakdown with Code Point Details

The Breakdown tab shows every character as a clickable card with its code point, Unicode block, plane, and ASCII/multi-byte classification. Click any card to load full details — all six format representations — in the left panel.

Configurable Separator

Choose how code points are separated in the output: space (default, readable), newline (one per line, easy to scan), comma (CSV-compatible, easy to parse programmatically), or none (bare concatenation, compact). Switch at any time without re-entry.

Full Unicode Range — Including Emoji & CJK

Handles all 149,000+ Unicode characters including emoji (U+1F600+), CJK ideographs, RTL scripts (Arabic, Hebrew), combining diacritics, supplementary plane characters, and any character that JavaScript's String.codePointAt() can represent.

Multi-Byte Character Detection

Characters above U+007F require multiple bytes in UTF-8 encoding. The tool identifies and highlights multi-byte characters in the breakdown tab and stats bar, making it immediately clear which characters require special handling in byte-oriented systems.

100% Browser-Based — Private & Instant

All conversion happens locally in your browser using JavaScript. No data is sent to any server. Works offline once the page has loaded. Safe for sensitive source code, credentials, and personal data.

Who Is This Unicode Converter Useful For?

Web developers and front-end engineers: Convert special characters to HTML entities for safe inclusion in HTML content, JavaScript escape sequences for string literals, or CSS unicode values for content properties. Essential for internationalisation (i18n) and localisation (l10n) work.
Software engineers and backend developers: Look up UTF-8 byte representations to understand memory layout, debug encoding issues in APIs and databases, and verify correct character handling in multi-language applications.
Security researchers and penetration testers: Convert characters to and from Unicode escape sequences to identify Unicode normalisation vulnerabilities, homoglyph attacks, and encoding-based injection vectors. Inspect supplementary plane characters that may bypass naive input validation.
QA engineers and testers: Generate Unicode test data across multiple formats for testing character encoding robustness in forms, databases, APIs, and file systems. The multi-byte indicator flags characters that commonly expose encoding bugs.
Linguists and localisation specialists: Identify code points for characters in non-Latin scripts, verify that CJK characters, emoji, and RTL text are correctly represented, and produce HTML entity strings for use in language-agnostic content.
Data scientists and analysts: Convert text data to its numeric code point representation for machine learning preprocessing, feature engineering, and text normalisation pipelines.
Designers and content creators: Look up the correct HTML entity for special characters (em dash, non-breaking space, copyright symbol, etc.) to use in HTML templates and CMS content fields.

What Is a Unicode Converter?

A Unicode converter is a tool that translates human-readable text into one or more of the numeric representations that computers use to store, transmit, and process characters — and reverses the process, turning numeric representations back into readable text. The numeric representations take several forms, each suited to different technical contexts: U+ hex notation for documentation and specification, HTML entities for safe HTML embedding, JavaScript escape sequences for source code, UTF-8 byte values for byte-level analysis, and decimal integers for programming and data processing.

The Unicode Standard, maintained by the Unicode Consortium, defines a code space of 1,114,112 possible code points (U+0000 to U+10FFFF), of which approximately 149,000 are currently assigned to specific characters. Code points are divided into 17 planes of 65,536 code points each. The Basic Multilingual Plane (BMP), Plane 0 (U+0000–U+FFFF), contains the characters used by most modern scripts and nearly all everyday text. Supplementary planes (Planes 1–16) contain historic scripts, rare CJK characters, mathematical symbols, and all emoji.

The difference between Unicode and the specific encoding formats (UTF-8, UTF-16, UTF-32) is important: Unicode defines what code point a character has. UTF-8, UTF-16, and UTF-32 define how to store that code point as bytes. UTF-8 is the dominant encoding on the web — it uses 1 byte for ASCII characters (U+0000–U+007F), 2 bytes for U+0080–U+07FF, 3 bytes for U+0800–U+FFFF, and 4 bytes for supplementary characters. This makes it backwards-compatible with ASCII while supporting the full Unicode range.

The six output formats in this tool each have specific practical uses. U+ Hex is the standard way to cite and document Unicode characters in specifications, articles, and code comments. HTML Decimal and Hex entities are used to safely embed any character in HTML source without ambiguity about encoding. JavaScript/CSS escape sequences allow non-ASCII characters to be written in source code as portable ASCII strings. UTF-8 bytes are the actual values transmitted over networks and stored in files. Raw Decimal is used in programming contexts where the numeric code point value is needed directly.

Benefits of Using a Unicode Converter

Eliminate Encoding Bugs Before They Reach Production

The majority of character encoding bugs in web applications fall into a small number of categories: characters that look identical but have different code points (homoglyphs), multi-byte characters that get truncated by byte-limited database columns, HTML content that breaks because a special character was not properly escaped, and JavaScript strings that throw errors because a supplementary-plane character was written as a single \uXXXX escape rather than a surrogate pair or \u{XXXXX}. A Unicode converter makes all of these issues visible before they cause problems — inspect any character's exact code point and all its format representations in seconds.

For security work specifically, the ability to convert between representations is essential for identifying encoding-based attacks. Unicode normalisation vulnerabilities — where two different byte sequences decode to the same visible character — can be detected by checking the exact code points involved. The UTF-8 byte representation reveals whether input validation that operates on bytes rather than code points is at risk of being bypassed.

For internationalisation and localisation work, a Unicode converter accelerates character research significantly. When localising an application for Arabic, Hebrew, Thai, or any script that requires special font or layout handling, quickly converting sample text to U+ notation and looking up the code points helps identify exactly which Unicode blocks are in use and whether the target environment supports them correctly.

For HTML and web development, the ability to instantly generate HTML entity strings eliminates manual lookup of entity codes. Characters like & (U+0026), < (U+003C), > (U+003E), " (U+0022), non-breaking space (U+00A0), em dash (U+2014), and right double quotation mark (U+201D) are needed regularly in HTML content. Converting their decimal or hex entities in one click is consistently faster and more accurate than manual lookup.

For JavaScript and TypeScript development, the JS escape output is directly usable in string literals. When working with characters that might be mangled by editors, version control systems, or code review tools, expressing them as \u0041 or \u{1F600} guarantees that the exact character is preserved regardless of the encoding of the file or the tools involved.

Why Unicode Conversion Matters in Modern Development

Unicode became the dominant character encoding standard on the internet in the early 2000s and is now essentially universal — over 97% of web pages use UTF-8 encoding. Despite this ubiquity, Unicode-related bugs remain among the most common and most subtle in web development. The reasons are structural: many developers understand that Unicode exists but have limited exposure to its details; many tools that should handle Unicode correctly have edge cases or limitations; and the gap between what a character looks like and what its byte representation is can be large and unexpected.

Emoji support illustrates this perfectly. Emoji were added to Unicode starting with the BMP's Miscellaneous Symbols block and later extended into supplementary planes. A single modern emoji like the flag of Japan (🇯🇵) is not a single Unicode code point — it is a sequence of two Regional Indicator characters (U+1F1EF and U+1F1F5). Other emoji use zero-width joiners (U+200D) to combine multiple code points into a single visible glyph. Skin tone modifiers (U+1F3FB–U+1F3FF) combine with base emoji. Each of these multi-code-point sequences has different UTF-8 byte lengths and different JavaScript string lengths. A string.length check that counts JavaScript UTF-16 code units rather than Unicode code points will give wrong answers for any emoji that requires surrogate pairs.

For security, the importance of Unicode conversion is even more direct. The Unicode homoglyph attack — where characters from different Unicode blocks look visually identical but have different code points — is a documented attack vector in phishing, domain spoofing, and code injection. The Latin "a" (U+0061), the Cyrillic "а" (U+0430), and the Greek "α" (U+03B1) are visually indistinguishable in most fonts but are completely different code points. A domain containing Cyrillic characters can look identical to its Latin equivalent. A Unicode converter makes these distinctions immediately visible.

How to Use the Unicode Converter

Select Your Direction

Use the Text → Unicode / Unicode → Text toggle at the top of the left panel. Text → Unicode encodes any text to your chosen format. Unicode → Text decodes escape sequences back to readable characters — supporting U+XXXX, \uXXXX, \u{XXXXX}, &#XXXX;, &#xXXXX;, and 0xHH hex byte formats.

Type or Paste Your Input

Enter any text in the input panel. All Unicode characters are supported. Click any of the four sample buttons — Hello, Emoji, Japanese, or Mixed — to load a pre-built example immediately. Output updates in real time as you type.

Choose Your Output Format

Click any format card in the left panel to set it as the active output — U+ Hex, HTML Decimal, HTML Hex, JS/CSS Escape, UTF-8 Bytes, or Raw Decimal. All six formats are computed simultaneously; switching the active format requires no re-processing.

Copy Per Format or Copy Active

Click the Copy button on any individual format card to copy that specific format's output without changing the active selection. Use the large Copy Result button at the top of the output panel to copy the currently active format.

Inspect the Character Breakdown

Switch to the Breakdown tab in the output panel to see every character as a clickable card showing its code point, Unicode block, plane, and active format value. Click any card to load the full six-format detail view in the left panel, showing all representations for that character simultaneously.

Adjust the Separator

In the left panel (desktop) or Options sheet (mobile), select Space, Newline, Comma, or None as the separator between code point values in the output. Use Newline for one-per-line output that's easy to scan; use Comma for programmatic parsing; use None for compact concatenation.

Common Use Cases for Unicode Conversion

HTML entity generation: Convert special characters (em dash, curly quotes, non-breaking space, trademark symbol, copyright symbol, mathematical operators) to their HTML decimal or hex entities for safe inclusion in HTML templates and CMS content fields where the raw character might cause parser issues.
JavaScript string literal encoding: Convert non-ASCII characters to \uXXXX or \u{XXXXX} escape sequences to create portable, ASCII-safe JavaScript string literals that are unambiguous regardless of source file encoding or editor configuration.
UTF-8 byte analysis: Convert any character to its UTF-8 byte representation to verify byte lengths for database column sizing (VARCHAR vs TEXT), network packet analysis, file format parsing, and binary protocol implementation.
Emoji and supplementary character debugging: Convert emoji and supplementary plane characters to their code points to understand why string.length returns unexpected values in JavaScript, why certain characters appear as replacement characters, and why input validation might behave unexpectedly.
Homoglyph detection: Paste visually similar text from different sources (a copied URL, a pasted username) and compare U+ Hex output to identify whether seemingly identical characters are actually different code points from different Unicode blocks.
CSS content properties: Convert characters to their 4-digit hex Unicode value for use in CSS content properties (e.g., content: "\2192" for →). The JS/CSS Escape format produces exactly this syntax.
Database and API debugging: When a character appears garbled in a database or API response, convert the garbled characters to their code points and compare against the expected code points to diagnose encoding mismatch between application layer, transport, and storage.
Internationalisation testing: Generate test strings containing characters from multiple Unicode blocks and scripts to verify that an application handles multi-byte UTF-8 characters correctly in all code paths — forms, database writes, API responses, PDF generation, email sending, and file creation.

Best Practices for Unicode in Development

Always use UTF-8 throughout your stack: The most common source of Unicode bugs is encoding mismatch — a UTF-8 file being read as Latin-1, a UTF-16 API response being treated as UTF-8. Standardising on UTF-8 for files, databases, APIs, and HTTP headers eliminates the majority of encoding issues.
Use codePointAt() instead of charCodeAt() in JavaScript: charCodeAt() returns UTF-16 code units, which gives wrong results for supplementary plane characters (emoji, many East Asian characters). codePointAt() returns the actual Unicode code point. Similarly, use for...of to iterate over Unicode scalar values rather than UTF-16 code units.
Specify character encoding explicitly in HTML: Always include <meta charset="UTF-8"> as the first element inside <head>. The browser uses the first 1024 bytes of the document to detect charset, and an explicit declaration prevents misdetection.
Use Unicode normalisation for text comparison: The same visible character can often be represented by multiple Unicode code sequences — for example, é can be U+00E9 (precomposed) or U+0065 U+0301 (e + combining accent). Always normalise to NFC or NFD before comparing text to avoid false mismatches.
Escape special HTML characters, not all non-ASCII: You only need to HTML-escape characters that have special meaning in HTML (&, <, >, ", ') — not all non-ASCII characters. UTF-8 encoded characters can appear directly in HTML served as UTF-8 without entities. Converting all non-ASCII to entities makes source code harder to read for no security benefit in a UTF-8 document.
Check the UTF-8 byte length for database column sizes: A VARCHAR(255) column stores 255 bytes, not 255 characters in multi-byte UTF-8. A single CJK character requires 3 bytes; an emoji may require 4. Use the UTF-8 Bytes output in this tool to quickly check byte length for any character.

Frequently Asked Questions

Q.What is the difference between U+ Hex and HTML Hex entity?

U+ Hex (e.g. U+0048) is the standard Unicode notation for specifying a code point — it is used in documentation, specifications, and code comments but is not directly usable in HTML source. HTML Hex entity (H) is the HTML/XML numeric character reference format using the same hex value — it is recognised by HTML parsers and browsers and can be used directly in HTML content. The hex digits are the same; the prefix and syntax differ.

Q.When should I use \u0048 vs \u{48} in JavaScript?

\uXXXX (exactly four hex digits) is the classic JavaScript unicode escape, supported since ES1. It only handles code points U+0000–U+FFFF (the Basic Multilingual Plane). \u{XXXXX} (variable hex digits in braces) was introduced in ES2015 and supports the full Unicode range including supplementary plane characters. Use \u{XXXXX} for emoji and any character above U+FFFF. This tool outputs \uXXXX for BMP characters and \u{XXXXX} for supplementary characters automatically.

Q.Why does JavaScript's string.length give unexpected values for emoji?

JavaScript uses UTF-16 encoding internally. Characters in the Basic Multilingual Plane (U+0000–U+FFFF) use a single 16-bit code unit, so string.length counts them as 1. Supplementary plane characters (including most emoji, U+10000+) require two 16-bit code units (a surrogate pair), so string.length counts them as 2. The correct way to count Unicode code points is to use the spread operator ([...str].length) or the string's Symbol.iterator, which iterates Unicode scalar values rather than UTF-16 code units.

Q.What is the UTF-8 byte count for common character types?

ASCII characters (U+0000–U+007F): 1 byte each. Latin Extended and common non-ASCII Western characters (U+0080–U+07FF): 2 bytes each. CJK unified ideographs and most other non-Latin scripts (U+0800–U+FFFF): 3 bytes each. Emoji and supplementary plane characters (U+10000–U+10FFFF): 4 bytes each. The UTF-8 Bytes output in this tool shows the exact byte values for any character, and the Breakdown tab labels each character as 'ascii' (1 byte) or 'multi' (2-4 bytes).

Q.What is a Unicode homoglyph attack?

A homoglyph attack uses Unicode characters from different scripts that are visually identical (or nearly identical) to characters from another script, to impersonate domains, usernames, or code identifiers. For example, the Cyrillic letter а (U+0430) looks identical to the Latin letter a (U+0061) in most fonts. A domain name using Cyrillic а appears identical to the Latin version but resolves differently. Converting suspicious text to U+ Hex instantly reveals if different-looking code points are masquerading as the same character.

Q.How do I decode \uXXXX escape sequences?

Switch to the Unicode → Text mode using the direction toggle at the top of the left panel. Paste your JavaScript unicode escape sequences (\u0048\u0065\u006C etc.) into the input panel. The decoded readable text appears instantly in the output panel. The decoder also handles U+XXXX notation, HTML decimal entities (H), HTML hex entities (H), \u{XXXXX} modern JS syntax, and 0xHH UTF-8 hex byte values — all in the same input simultaneously.

Q.Does this tool support non-Latin scripts like Arabic, Chinese, and Japanese?

Yes, fully. The tool supports all Unicode code points that JavaScript can represent — the entire range from U+0000 to U+10FFFF. This includes all Latin scripts, Cyrillic, Arabic, Hebrew, all CJK unified ideographs, Hiragana, Katakana, Hangul, Thai, Devanagari, and every other script in the Unicode Standard, plus emoji, mathematical symbols, and all supplementary plane characters.

Q.Is my text sent to a server when I use this tool?

No. All conversion happens entirely in your browser using JavaScript. No data is sent to any server at any point. The tool works offline once the page has loaded and is completely private — safe for use with source code, credentials, personal data, or any sensitive content.

Conclusion

Unicode is the foundation of all modern text on the internet — every character in every language, every emoji, every symbol, every piece of text that flows through any digital system today is ultimately a Unicode code point. Understanding and working correctly with Unicode code points is not optional for developers, security researchers, localisation specialists, and anyone who handles international text professionally.

This free Unicode converter makes that work faster and more reliable: six output formats simultaneously, per-format copy buttons, bidirectional encode and decode, a character-by-character breakdown with full code point details, multi-byte character detection, configurable separators, and full support for the complete Unicode range including emoji and supplementary planes. All processing runs in your browser, privately, in real time, with no server uploads and no sign-up required.

Whether you are generating HTML entities for a content template, producing JS escape sequences for a string literal, debugging UTF-8 byte lengths for a database schema, or checking whether a suspicious character is a homoglyph — type your text, choose your format, and copy the output.
