About the Unicode Calculator
The Unicode Calculator turns a character (including emoji and non-Latin scripts) into its Unicode code point (U+XXXX), decimal value, and UTF-8 bytes — or the other way, from a code point to a character. It supports the full Unicode range up to U+10FFFF.
Useful when working with internationalisation, emoji, or debugging text encodings.

Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
