• parse_peak_bytes: the most memory the parser held at once;

• input_bytes: size of the decoded UTF-8 input;

• encoding: the encoding the input was decoded from;

• encoding_source: where that encoding came from: "bom" (a byte-order mark), "argument" (the encoding argument), "meta" (a ⁠<meta>⁠ declaration), "default" (none of these, so UTF-8), or "string" for character input, which is already decoded;
