Greek characteres in a file

Question

Hello,
i've a file which is encoded in unicode. This file has some normal characters and some special characters wich are greek.
Now i need to read this file using utl_file and map the information to a database table.
The table as some columns as varchar2 and some as nvarchar2 to store the greek characters.
Before execute the procedure, the NLS_LANG is set to Greek and what happen is after inserting data into table, i cannot read the greek characters anymore.
My idea is that the problem is about the "unicode" of the file.
Can you help, please,
Thanks,
Pedro Ribeiro

Hello,

Answering you question the output for NLS_DATABASE_PARAMETERS is
NLS_LANGUAGE     AMERICAN
NLS_TERRITORY     AMERICA
NLS_CURRENCY     $
NLS_ISO_CURRENCY     AMERICA
NLS_NUMERIC_CHARACTERS     .,
NLS_CHARACTERSET     AL32UTF8
NLS_CALENDAR     GREGORIAN
NLS_DATE_FORMAT     DD-MON-RR
NLS_DATE_LANGUAGE      AMERICAN
NLS_SORT     BINARY
NLS_TIME_FORMAT     HH.MI.SSXFF AM
NLS_TIMESTAMP_FORMAT     DD-MON-RR HH.MI.SSXFF AM
NLS_TIME_TZ_FORMAT     HH.MI.SSXFF AM TZR
NLS_TIMESTAMP_TZ_FORMAT     DD-MON-RR HH.MI.SSXFF AM TZR

NLS_NCHAR_CONV_EXCP     FALSE
NLS_NCHAR_CHARACTERSET     AL16UTF16
NLS_RDBMS_VERSION     9.2.0.8.0
but in unix I put the line NLS_LANG=GREEK_GREECE.EL8ISO8859P7; export NLS_LANG; in my .profile.
In PL code I put
EXECUTE IMMEDIATE 'alter session set nls_language=greek';
EXECUTE IMMEDIATE 'alter session set nls_territory=greece';
I have the regional setting from Windows to greek.
If you can think in anything that can be missing, please tell me.
