With binary set, parse(\"a,\\r\") returns the fields \"a\" and \"\\xFF\". On UTF-8 flagged input the last field is a UTF-8 flagged string holding that lone byte, which is malformed UTF-8. The same input with a non-empty last field is rejected as an error.\n\nA CRLF file read line by line and chomped ends this way when its last column is empty, so the application receives a byte that is not in its input."
