FAQ
How is each character encoded?
Each character’s Unicode code point is written in binary and padded to at least 8 bits, with a space between characters.
What happens if my binary is invalid?
When decoding, any token that is not made of 0s and 1s stops the conversion with a small error, so you can fix the input.
Can it handle emoji?
Yes — characters beyond the basic set are encoded by their full code point and decode back correctly.
