separator
.
new output separator output_obj

object OOChannel.obj_output_channel which receives Unicode characters
and converts line separators (all of CR, LF, CRLF, NEL, LS, PS) to

and output lines. All of CR, LF, CRLF, NEL, LS, PS,
as well as FF (formfeed) are recognised as a line separator.
new output_line ~sp output_obj
