Hex and Text

Good to know

• The bytes depend on the encoding, not just the text. "ç" is c3 a7 in UTF-8 and a single e7 in windows-1254 — same character, different bytes.
• Reading is forgiving: spaces, colons, commas, line breaks, 0x and \x are all stripped before parsing, so a dump pasted from anywhere usually just works.
• Writing is not: the separator, the prefix and the letter case are yours to choose, and they only shape the output.
• Everything happens in your browser. Nothing you type is sent to the server or stored anywhere.
