17# followed by ".HODE" and end with "\n.SLUTT" followed by an optional
18# separator (any number of " ", "\t", "\n" or "\r"), might have BOM at
19# the start and following ".HODE" near the start there is "..OMR=C3=85DE"
20# (either UTF-8, ISO-8859-1 or some 7 bit Norwegian charset based on
21# ASCII) , "..TRANSPAR", "..TEGNSETT " followed by the charset and a
22# separator, as well as "..SOSI-VERSJON " followed by the format
23# version and a separator.

25# FIXME figure out how to accept any of [space], [tab], [newline] and
26# [carriage return] as separators, not only line end.
