FAQ

How is text converted to binary?

Each character is encoded as UTF-8 bytes, and each byte is written as 8 bits. For example, the letter "A" is 01000001.

What format does it expect to decode binary?

Groups of 8 bits (0s and 1s) separated by spaces. Any other format will show an error.

Does it support characters outside plain ASCII?

Yes. Since it uses UTF-8, accented letters, emoji and other Unicode characters convert correctly, just using more than one byte each.
