How do you type ñ on an English keyboard? What's the code point for 🎉? How do you escape a trademark symbol in JavaScript? Unicode answers all of these, but its complexity intimidates many developers. Understanding Unicode conversion makes you comfortable with any character in any language.
What Is Unicode Converter?
Unicode assigns a unique code point (number) to every character in every script — over 149,000 characters across 161 scripts. Our Unicode Converter transforms text to code points (U+0041), JavaScript escapes (\u0041), HTML entities, and UTF-8 byte sequences.

Converting Special Characters
See the multiple representations of a single character:
// Character: é (e with acute accent)
Unicode: U+00E9
HTML entity: é
JavaScript: \u00E9
UTF-8 bytes: C3 A9
Decimal: 233
// Emoji: 🚀 (rocket)
Unicode: U+1F680
JavaScript: \uD83D\uDE80 (surrogate pair)
HTML: 🚀
UTF-8 bytes: F0 9F 9A 80Pro Tips
- Use \u{1F680} in modern JavaScript instead of surrogate pairs for emoji
- JavaScript's String.length counts UTF-16 code units, not characters — emoji have length 2
- CSS can reference Unicode with content: '\00E9' in pseudo-elements
- Normalize Unicode strings before comparison — 'é' can be either U+00E9 or U+0065 U+0301
