Unidac Oracle charset Problem.

[wbjsoft]

I use oracle server charset - US7ASCII with korean.
It works well with UniConnection.SpecificOptions.Values['Charset']
:= 'US7ASCII'

but not work with these situations.
client side query,
clientdataset1.commandtext := 'update table1 set field1 = :field1 ';
clientdataset1.params.parambyname('field1').AsString = '한글';
clientdataset1.execute;
after executing , field1 = '????'

and it dosen't work with CLOB

when I used your DBExpress Driver Oracle, It works well. I think.

but it dosen't work after migration to UniDac.

thank you.
