| 2019-07-28 | email: Support email with mixed encoding of characters.•••Prior to this, parse-email would accept email in the form of a
string. A string is constrained to use the same encoding for all its

different encoding schemes. Therefore, it is more correct that
parse-email deals with bytevectors instead of strings.
