Function atom_bytes 

pub fn atom_bytes(bytes: &[u8]) -> String

human-atom-bytes-v1: a repository-derived value that is raw bytes, not text, rendered under the same law as atom. At most the first two hundred bytes are kept with a literal ... appended inside the quotes when any were omitted; printable ASCII stays literal with quote and backslash escaped, and every other byte becomes the lowercase \u00xx escape of its value, so no byte is ever active terminal syntax and no Unicode scalar is invented for bytes that never encoded one.
