Unicode Encoder Decoder

Unicode is a universal character encoding standard that assigns a unique number (called a code point) to every character across all writing systems. Code points are typically written in the format U+XXXX, where XXXX is a hexadecimal number. The range U+0000 to U+FFFF is the Basic Multilingual Plane (BMP), which covers most common characters. Supplementary characters (like emojis) use code points from U+10000 to U+10FFFF.

For example, the Latin letter A has code point U+0041, the Euro sign € is U+20AC, and the globe emoji 🌍 is U+1F30D.

Why Use Unicode Encoding?

• Universal representation of text across all languages and scripts
• Foundation of modern web technologies (HTML, JSON, JavaScript)
• Essential for internationalization (i18n) and localization (l10n)
• Used in escape sequences for strings in programming languages
• Understanding Unicode is critical for proper text processing

1. Encode text — Type or paste text into the left panel, then click Encode to convert each character to its Unicode code point.
2. Decode Unicode — Type or paste U+XXXX values into the right panel, then click Decode to convert them back to text.
3. Toggle options — Use Uppercase, U+ prefix, and Add spaces to control the output format.
4. Swap & Clear — Click Swap to exchange encode/decode values, Clear All to reset everything.

The encoder converts each character to its full Unicode code point (up to 6 hex digits). The decoder accepts formats like U+0041, 0041, \\u0041, and 0x0041.

• Web development — Use Unicode escape sequences (\\u0041) in JavaScript strings for non-ASCII characters.
• Internationalization — Identify code points of characters from different languages for proper encoding support.
• Debugging text encoding — Diagnose mojibake (garbled text) by examining the underlying code points.
• Data processing — Convert between Unicode code points and text for CSV, JSON, or database operations.
• CTF & puzzles — Decode hidden messages encoded as Unicode code point sequences.
