By specifying the new 'separator' option they will instead be separated by user provided string and have separator semantics rather than terminator semantics. The separator string can contain the literal formatting codes %n and %xNN allowing it to be things that are otherwise hard to type such as %x00, or comma and end-parenthesis which would break parsing.
