How to use

Type or paste text and choose what each number should represent.
“UTF-8 bytes” gives the raw byte values (0–255) a program would store — useful for byte arrays and protocols.
“Unicode code points” gives one number per character, such as 233 for é or 128512 for 😀.
To decode, switch modes and paste numbers separated by spaces, commas or line breaks. Make sure “Values” matches how the numbers were made.

Why do bytes and code points give different numbers?

A code point identifies a character; UTF-8 then stores it in 1–4 bytes. “é” is code point 233 but the two bytes 195 169 in UTF-8.

Is the decimal value the same as the HTML &#…; number?

Yes — the code point option gives the same number you would use in an HTML numeric reference such as é.
