Byte stuffing like in https://datatracker.ietf.org/doc/html/rfc1662#section-4.2 except that we use a long byte prefix to make it easier to find and less chance of constantly escaping every random 255th byte

Pick some 7 bytes prefix P, something less likely to occur in erlang term_to_binary or utf8 encodings.

P = f5, f6, f7, f8, f9, fa, fb

One byte H (=fc) is the header byte. The header tag: P|H = f5, f6, f7, f8, f9, fa, fb, fc

Another X (=fd) is the escape header byte. The whole escape prefix is P|X = f5, f6, f7, f8, f9, fa, fb, fd
