[Lazarus] German Umlauts and Oracle Connection

[John Landmesser]

i get Citynames from a oracle Database, but i get for example "Gie?en" 
instead of "Gießen" In a TDBGrid.

I tried different Charset in my OracleConnection.Charset as mentioned 
from Oracle on

http://docs.oracle.com/cd/B28359_01/server.111/b28298/applocaledata.htm#CIAJAGCB

but without success!


If i put a Tedit on my form, i can write "Gießen", so it has to be a 
setting in OracleConnection?!!

MainForm.Font.CharSet Is DEFAULT_CHARSET

Tipps are welcome!

never arrived?? )
