About the Unicode & ASCII Converter

Computers store each character as a number. This converter shows those numbers in the formats developers use most, and turns them back into text.

How to use it

Type text in the left box and choose a format. The encoded result appears on the right.
To decode, paste encoded text into the right box and the plain text appears on the left.
The table below shows each character with its code point and UTF-8 bytes.

Questions

What is the difference between a code point and UTF-8?

A code point is the number Unicode gives a character, such as U+0416 for Ж. UTF-8 is the most common way to store that number, using 1 to 4 bytes per character.

Does it handle emoji?

Yes. Emoji and other characters beyond U+FFFF are converted correctly in every format.

Why does decoding fail?

The input has to match the selected format. For example, Base64 can only contain letters, digits, + and /, and hex needs pairs of 0–9 and A–F.
