Frequently Asked Questions

What is hex encoding?
Each byte of the text (UTF-8) is written as two hexadecimal digits (0–9, A–F). So one ASCII character = 2 hex digits.
Format of output?
By default a continuous hex string. You can optionally add spaces between bytes for readability.
Does it support Unicode?
Yes. Text is encoded as UTF-8 first, so multi-byte characters produce multiple hex pairs.
