Unicode encoder decoder tool converts text, emojis, symbols to Unicode code points (U+XXXX format) and decodes Unicode back to readable text. Perfect for developers, designers, and content creators working with international text.
What is Unicode Encoding?
Unicode is a universal character encoding standard that assigns a unique number (code point) to every character across all writing systems. Unlike legacy encoding systems like ASCII (which only supports 128 characters) or ISO-8859-1 (256 characters), Unicode supports over 149,813 characters including:
📝 Text Characters
Letters from 161 modern and historic scripts including Latin, Cyrillic, Greek, Arabic, Hebrew, Chinese, Japanese, Korean, and Devanagari.
😀 Emojis & Symbols
3,664 emojis, mathematical symbols, currency symbols, arrows, geometric shapes, and dingbats for complete visual communication.
🔠 Technical Symbols
Control characters, formatting marks, private use characters, and compatibility characters for technical applications.
How to Use Unicode Encoder Decoder Tool
Step 1: Text to Unicode Encoding
- Enter Text: Type or paste your text, emojis, or symbols in the input field
- Click Encode: Press the blue “Encode to Unicode” button
- Get Results: Text converts to Unicode code points (U+XXXX format)
- Copy Output: Use the copy button to transfer results to clipboard
Step 2: Unicode to Text Decoding
- Enter Unicode Codes: Paste Unicode code points (U+0048 U+0065 U+006C U+006C U+006F)
- Click Decode: Press the purple “Decode Unicode” button
- View Text: Unicode codes convert back to readable text
- Verify Output: Check character rendering matches original intent

Practical Applications of Unicode Encoding
🌐 Web Development
Ensure proper character rendering across browsers, handle user input in multiple languages, and prevent encoding issues in forms and APIs.
📱 Mobile Apps
Handle emoji input, support international keyboards, and ensure consistent text display across iOS and Android platforms.
💾 Database Management
Store multilingual content correctly, prevent data corruption, and handle character set conversions between systems.
Frequently Asked Questions (FAQ)
1. What’s the difference between Unicode and ASCII?
ASCII (American Standard Code for Information Interchange) is a 7-bit encoding supporting 128 characters for basic English text. Unicode is a universal standard supporting 149,813+ characters across all languages. While ASCII is limited to English letters, digits, and basic symbols, Unicode includes international scripts, emojis, mathematical symbols, and technical characters.
2. How do I convert emojis to Unicode?
Use our Unicode encoder tool: Paste any emoji (😀, 👍, ❤️) in the input field and click “Encode to Unicode”. Each emoji converts to its unique Unicode code point (U+1F600 for 😀). Complex emojis with skin tones or combinations use multiple code points separated by spaces.
3. Is Unicode encoding secure for passwords?
Unicode encoding itself doesn’t provide security – it’s for character representation. For password security, use hashing algorithms (bcrypt, Argon2) instead. Unicode encoding helps ensure password characters are correctly stored across systems but doesn’t encrypt or protect the data.
4. What’s the maximum Unicode value?
The Unicode standard defines 1,114,112 possible code points from U+0000 to U+10FFFF. Currently, 149,813 characters are assigned across 161 scripts. The highest assigned code point is U+10FFFF, though not all positions are used – many ranges are reserved for future expansion or private use.
5. Can Unicode handle right-to-left languages?
Yes, Unicode fully supports bidirectional text including Arabic (U+0600-U+06FF), Hebrew (U+0590-U+05FF), and other right-to-left scripts. Unicode includes special control characters (U+200E, U+200F) for explicit directionality control when needed for mixed-direction text.
