Unicode is the foundation of modern text encoding, supporting virtually every written language and symbol used worldwide. Our free Unicode Converter makes it easy to work with Unicode code points, whether you're a developer debugging encoding issues, a student learning about internationalization, or anyone who needs to convert between text and Unicode representations. The tool supports bidirectional conversion (text β Unicode), multiple output formats (hex, decimal, JavaScript escapes), and all Unicode characters including emojis and international scripts. With instant results and copy functionality, it's your go-to resource for all things Unicode.
Unicode is an international standard that assigns a unique numeric code to every character across all writing systems. Our Unicode Converter translates between human-readable text and these numeric representations. It supports: Code Points - The standard U+XXXX format, Escape Sequences - Programming language formats (\uXXXX), HTML Entities - &#xhhhh; and &#dddd; formats, Multiple Encodings - UTF-8, UTF-16 representations. The converter handles the entire Unicode range: Basic Multilingual Plane (U+0000 - U+FFFF) and Supplementary planes (U+10000 - U+10FFFF) for emojis and historic scripts. Whether you need to encode special characters for programming, decode Unicode escapes, or simply explore character codes, this tool provides comprehensive Unicode support.
Complete Unicode Support covers all 143,000+ Unicode characters including emojis. Multiple Output Formats generates \uXXXX, U+XXXX, &#xhhh;, decimal, and more. Bidirectional Conversion converts both text-to-Unicode and Unicode-to-text. Emoji Support handles all 3,600+ emojis with code points. Format Auto-Detection intelligently recognizes input format. Copy Formatted Results with one-click copying for each format. Block Explorer view characters organized by Unicode blocks. Character Information displays name, category, and properties. Real-time Conversion shows results as you type. Browser Processing ensures privacy - no data sent to servers. Mobile Friendly works on all devices without installation. Free and Unlimited with no registration required.
The conversion process is straightforward: Text to Unicode: Each character is looked up in the Unicode database, Its code point is retrieved (e.g., 'A' = U+0041), Code point formatted in selected output format, Process repeats for each character. Unicode to Text: Input parsed for code points, Each code point converted to a character, Characters combined into final text. Supported Formats: U+0048 - Standard Unicode notation, \u0048 - JavaScript/C escape, \x48 - Hex escape, H / H - HTML decimal/hex, 0x0048 - Programming hex literal, 72 - Decimal value. The tool automatically detects input format and converts accordingly. All processing happens locally for privacy and speed.

Using the Unicode Converter is simple and requires no setup: First, open the converter in your web browser - no installation or registration needed. Second, select your conversion direction using the toggle: choose 'Text to Unicode' to convert readable text into code points, or 'Unicode to Text' to decode Unicode values back into text. Third, choose your desired output format from the dropdown menu: standard U+XXXX notation, JavaScript escape sequences (\uXXXX), HTML hex entities (&#xXXXX;), HTML decimal entities (&#DDDD;), or raw decimal values. Fourth, enter your input in the text area: for Text to Unicode, type or paste the text you want to convert; for Unicode to Text, enter Unicode values in any supported format (U+0048, \u0048, H, or 72). Finally, click the 'Convert' button or press Enter to process your input. Your results appear instantly below the input area. For text-to-Unicode, you'll see code points for each character. For Unicode-to-text, you'll see the decoded characters. Use the copy button to save results to your clipboard, or continue with additional conversions as needed.
Input Format Flexibility: The converter accepts multiple Unicode input formats automatically - U+0048, \u0048, H, H, and raw decimal values all work. You can mix formats in the same input. Font Compatibility: Remember that displaying Unicode characters requires fonts that support them. If you see boxes or question marks instead of characters, your system needs appropriate fonts installed. For emojis, modern operating systems include emoji fonts by default. UTF-8 Encoding: When working with files and databases, always use UTF-8 encoding to ensure Unicode characters are preserved correctly. This is the standard encoding for modern web applications and supports all Unicode characters. HTML Entity Selection: Use &#xhhhh; (hexadecimal) for HTML when possible - it's more compact than decimal and easier to read. Both work identically in browsers. JavaScript String Literals: When embedding Unicode in JavaScript code, use \uXXXX for characters in the Basic Multilingual Plane (BMP) and \u{X} for characters outside BMP (like emojis above U+FFFF). Testing with Known Values: Verify the converter works correctly by testing with known values. For example, 'Hello' should convert to U+0048 U+0065 U+006C U+006C U+006F. The letter 'Γ©' should convert to U+00E9. Copying Results: Always use the copy button rather than manual selection to ensure you capture the complete result without accidentally missing characters. This is especially important for long Unicode sequences. Mobile Considerations: While the tool works on mobile devices, entering long Unicode strings on small screens can be error-prone. Use desktop computers for complex conversion tasks when possible. Educational Exploration: Use the tool to explore Unicode blocks by entering single characters and observing their code points. This helps understand how Unicode organizes characters by script and type.
This is a reference and conversion tool with some limitations: Conversion only - doesn't render all characters (depends on your device's fonts), No font information - doesn't show what font contains a character, General purpose - specialized Unicode tools may offer more features for researchers, Educational focus - designed for common use cases, not exhaustive Unicode exploration.
Unicode is a universal character encoding standard that assigns a unique number to every character used in written languages worldwide. Before Unicode, different systems used incompatible encodings (ASCII, EBCDIC, various regional standards), causing text corruption when shared. Unicode solves this by providing a single standard. Key facts: Supports over 143,000 characters, Covers 150+ writing systems (Latin, Arabic, Chinese, etc.), Includes emojis and symbols, Backwards compatible with ASCII (first 128 chars), Used by 95%+ of websites globally. You need Unicode support to: Display international text correctly, Handle emojis and special symbols, Ensure cross-platform compatibility, Future-proof your applications, Support global users.
Every Unicode character has a unique code point - a hexadecimal number prefixed with U+. The code point identifies the character regardless of how it's encoded in memory. Examples: U+0048 = 'H' (same as ASCII), U+00E9 = 'Γ©' (Latin small e with acute), U+4E2D = 'δΈ' (Chinese character), U+1F600 = 'π' (grinning face emoji). Code Point Ranges: U+0000 - U+007F: Basic Latin (ASCII), U+0080 - U+00FF: Latin-1 Supplement, U+0100 - U+017F: Latin Extended-A, U+4E00 - U+9FFF: CJK Unified Ideographs (Chinese), U+1F600 - U+1F64F: Emoticons. Encoding: Code points are abstract numbers - they must be encoded as bytes. UTF-8 (1-4 bytes per char) is most common, UTF-16 (2-4 bytes) used by Windows/Java, UTF-32 (4 bytes) fixed width.
Unicode and UTF-8 are related but different concepts: Unicode is the character set - a list assigning numbers to characters. UTF-8 is an encoding - a way to store those numbers as bytes. Analogy: Unicode is the phone book with names and numbers, UTF-8 is how you dial those numbers. Unicode provides the code points (U+0048 = H), UTF-8 defines how to represent U+0048 as bytes (0x48). UTF-8 Details: Variable width: 1-4 bytes per character, ASCII compatible: first 128 chars same as ASCII, Self-synchronizing: easy to find character boundaries, Most common: used by 95%+ of websites. Other Encodings: UTF-16: Fixed 2 or 4 bytes, UTF-32: Fixed 4 bytes (wasteful), ASCII: 7-bit, limited to 128 chars.
Different languages handle Unicode differently: JavaScript: Use \uXXXX for BMP characters, \u{X} for any Unicode, 'Hello \u0041' = 'Hello A', Emojis: \u{1F600} = 'π'. Python: Use \uXXXX or \UXXXXXXXX, '\u0048\u0065\u006c\u006c\u006f' = 'Hello', Supports Unicode source files with # -*- coding: utf-8 -*-. Java: Use \uXXXX in strings, String s = '\u0048\u0065\u006c\u006c\u006f';, Source files should be UTF-8 encoded. HTML: Use &#xhhhh; (hex) or &#dddd; (decimal), H = 'H', é = 'Γ©', Named entities: & = &, < = <. CSS: Use \hhhh in content property, content: '\0048'; = 'H'. Database: Use NVARCHAR or VARCHAR with UTF-8 collation.
Yes! Emojis are standard Unicode characters with their own code points. Popular Emoji Code Points: U+1F600 π Grinning Face, U+1F602 π Face with Tears of Joy, U+1F44D π Thumbs Up, U+2764 β€οΈ Red Heart, U+1F389 π Party Popper, U+1F680 π Rocket, U+1F4A1 π‘ Light Bulb, U+2615 β Hot Beverage. Emoji Conversion: Enter emoji β Get U+1F600, Enter \u{1F600} β Get emoji (JS), Supports all 3,600+ emoji characters, Includes skin tone modifiers, Includes combined emojis (families, couples). Note: Some older systems don't display all emojis, but the Unicode conversion works regardless of display capabilities.
These represent the same information in different formats: Unicode Code Point: U+0048 (standard notation), U+1F600 (for emojis), The abstract character number. Escape Sequences: \u0048 - JavaScript/C escape, \x48 - Hex escape, H - HTML decimal, H - HTML hex, %48 - URL encoding. Conversion: U+0048 β \u0048 (for code), U+0048 β H (for display), U+0048 β H (for HTML), U+0048 β %48 (for URLs). Our converter generates all these formats from a single input.
Common Unicode issues and solutions: Mojibake (garbled text): Problem: Text displays as ΓΒ© instead of Γ©, Solution: Re-encode with correct character set, Cause: UTF-8 text read as Latin-1. Missing Characters: Problem: Boxes or ? shown instead of characters, Solution: Use a font that supports those Unicode ranges, Cause: System font doesn't include those glyphs. Escape Sequences Showing: Problem: \u0048 displayed instead of H, Solution: Unescape the string before display. Database Issues: Problem: Special chars stored as ???, Solution: Use UTF-8 collation, Cause: Database column set to ASCII. File Encoding: Problem: Source file shows garbled comments, Solution: Save as UTF-8 with BOM (if needed).
