Re: Net::Z3950 and diacritics

I don't see how you can get a result for your search if you're using @attr 1=7. 7 is the USE attribute for an ISBN search, and your term is the local system number, I think (use attribute=12)

When I do that search (@attr 1=12 3118006) against the LC bib file, using Net::Z3950 in a program essentially the same as yours, the USMARC record returned is 860 bytes long. Here's a formatted dump of the record:

The "?" in the 245 and 600 fields are 0xE8, the MARC-8 code for combining umlaut/diaeresis.

It's puzzling that the record you got has a different length--not sure what's going on there.

  # define sum constants
  my $DATABASE = 'voyager';
  my $SERVER   = 'z3950.loc.gov';
  my $PORT     = '7090';

  # create a LOC (Voyager) 001 query
  my $query = "[EMAIL PROTECTED] 1=7 3118006";

  # create a z39.50 object
  my $z3950 = Net::Z3950::Manager->new(databaseName => $DATABASE);

  # assign the object some z39.50 characteristics
  $z3950->option(elementSetName => "f");
  $z3950->option(preferredRecordSyntax =>
Net::Z3950::RecordSyntax::USMARC);
  # connect to the server and check for success
  my $connection = $z3950->connect($SERVER, $PORT);

  # search
  my $results = $connection->search($query);

  # get the found record and turn it into a MARC::Record object
  my $record = $results->record(1);
  $record = MARC::Record->new_from_usmarc($record->rawdata());

  # create a file name
  my $id = time;

  # write the record
  open MARC, "> $id.marc";
  print MARC $record->as_usmarc;
  close MARC;


This process works just fine for records that contain no diacritics, but
when diacritics are in the records extra characters end up in my saved
files, like this:

Notice how Dürer got munged into Dˆ®urer, twice, and consequently the
record length is not 901 but 903 instead.

Some people say I must be sure to request a specific character set from
the LOC when downloading my MARC records, specifically MARC-8 or
MARC-UCS. Which one of these character sets do I want and how do I tell
the remote database which one I want?
