Example
Input
Hi 🎉
Output
72 105 32 127881
This is the result of clicking "Text → Decimal". H=72, i=105, space=32, and the emoji 🎉 is handled as a single code point (its surrogate pair combined) to become 127881.
Unicode code points and decimals
Shows the decimal value of each character's Unicode code point.
| Concept | Details |
|---|---|
| Code point | The unique Unicode number of a character — written U+XXXX in hex |
| Decimal value | The same point in decimal — 가 = U+AC00 = 44032 |
| Combined glyphs | Families, flags and emoji-looking characters are often multiple code points |
| Reverse | Paste decimal values to get the characters back |
FAQ
- What is the number based on?
- It shows each character's Unicode code point (codePointAt) value in decimal.
- Can emoji be converted too?
- Yes. Surrogate pairs are handled correctly and converted into a single code point.
- What happens if I enter an invalid number during decode?
- An error message tells you the code point value isn't valid.
- Are U+AC00 and 44032 different?
- Same number, different notation — U+ is hexadecimal (AC00), 44032 is decimal.
- Why does one "letter" give several numbers?
- Emoji and combining characters often consist of multiple code points, shown space-separated.
