Oracle fields

Oracle 8, Delphi 2006, want to use ADO for access. I want to create table
with fields:
unicode varchar 200
unicode memo
integer

What oracle datatype to use. I used nvarchar2(200), nvarchar2(4000) and
integer. Table was created, but when i open it, delphi maps to fields of
type ftString, ftString and ftBCD. I need ftWideString, ftWideMemo and
ftInteger. If I create fields by myself with this type I get error when
inserting records with Insert/Post that character set doesn't match or
something like that.
