Frequently asked questions
How is non-ASCII text handled?
Text is encoded as UTF-8 first, so each character becomes one or more 8-bit bytes that round-trip correctly.
What format does the binary use?
Each byte is shown as 8 binary digits separated by spaces, which is also the format expected when decoding.
