Hi Monks,

I am having some problems when getting some data from a MS-SQL server using DBD::Sybase: the encoding fails.

I am geting those errors : 

DBD::Sybase::st fetchrow_hashref failed: OpenClient message: LAYER = (
+0) ORIGIN = (0) SEVERITY = (9) NUMBER = (99)
Message String: Some character(s) could not be converted into client's
+ character set.  Unconverted bytes were changed to question marks ('?
+')
OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (9) NUMBER = (
+99)
Message String: Some character(s) could not be converted into client's
+ character set.  Unconverted bytes were changed to question marks ('?
+')

The characters are most likely to be country (Denmark) specific characters (æ ø å) but they are included in UTF-8. i am calling the db like this : my $dbh = DBI->connect("DBI:Sybase:server=$SERVER", $LOGIN, $PASSWD); freetds.conf : 

host = localhost
port 1433
tds version = 8.0
charset = UTF-8

(the server is not actually at localhost but a tunnel)

I tried : 

my $dbh = DBI->connect("DBI:Sybase:server=$SERVER;charset=CP1252", $LO
+GIN, $PASSWD);

but it does not help.

i added a variable to get some more logs from Freetds: export TDSDUMP=/tmp/freetds.log

I searched extensivly on google about this, and there is actually quite a lot of problems with M$ using CP1252 encoding...

I think the problem is that the MS-SQL server output is encoded in CP1252 and the Freetds decodes it as it were ISO-8859-1.
