Cant's select columns with umlaute

Hello All,

I try to established a DB-Link from Oracle 11g to a MSSQL 2000 database but it doesn't work. 

We install on Centos 5.1 (Linux 64bit).
Our database is Oracle 11.1.0.6.0 plus bugfix 7389110 and we installed the "linux.x64_11gR1_gateways".
I configured freetds and uinixodbc (see below)

I already told the unixodb folk about the problem, but they told me: ask the freetds folk. So I do now and I hope you can help me?

Here is my configuration and the problem.

When I try to connect using isql I get the following message:

 

SQL> isql combandb UN PW

Connected! |

SQL> select ID, Ort, Straße from x_lt;

ISQLERROR: Could not SQLPrepare

 

Here is the SQL-Log

Isql> select * from x_lt

Works well, but umlaute are missing.

 

Any idea is welcome!
