The function was written by inspection of a particular file, and might be wrong for other files; see “Details” for a note on character translation.

a connection or a character string giving the name of the file to load.
optional signed number indicating the longitude in degrees East.
optional signed number indicating the latitude in degrees North.
a character value that indicates the encoding to be used for
this data file, if it is textual. The default value for most functions is
"latin1", which seems to be suitable for files containing text written in
English and French.
a flag that turns on debugging. The value indicates the depth within the call stack to which debugging applies.
if provided, the action item to be stored in the log. This parameter is typically only provided for internal calls; the default that it provides is better for normal calls by a user.

The header is converted to ASCII format prior to storage in
the metadata slot, so that e.g. a degree sign in the original file will
become a ? character in the header. This is to prevent problems
with submission of oce to the CRAN system, which produces NOTEs
about UTF-8 strings in data (on some build machines, evidently depending
on the locale on those machines). This character substitution
is at odds with the oce philosophy of leaving data intact, so
it will be reverted, if CRAN policy changes or if the developers
can find a way to otherwise silence the NOTE.
