Error 2803 Secondary index uniqueness violation error utf-8 impact? - response (4) by jld@fitc

Hi there,
probably this explains the problem
CREATE MULTISET TABLE test.geo_dim2 ,NO FALLBACK ,
     NO BEFORE JOURNAL,
     NO AFTER JOURNAL,
     CHECKSUM = DEFAULT,
     DEFAULT MERGEBLOCKRATIO
     (
      GEO_SK BIGINT GENERATED ALWAYS AS IDENTITY
           (START WITH 1
            INCREMENT BY 1
            MINVALUE 1
            MAXVALUE 2147483647
            NO CYCLE),
      COUNTRY_ISO_A2 CHAR(2) CHARACTER SET UNICODE NOT CASESPECIFIC NOT NULL,
      CITY_TXT VARCHAR(100) CHARACTER SET UNICODE NOT CASESPECIFIC NOT NULL,
      ZIP_CODE VARCHAR(30) CHARACTER SET UNICODE NOT CASESPECIFIC NOT NULL)
UNIQUE PRIMARY INDEX ( GEO_SK )
UNIQUE INDEX ( COUNTRY_ISO_A2 ,CITY_TXT ,ZIP_CODE );
insert  into test.geo_dim2 (country_iso_a2, city_txt, zip_code) values ('GR','ΚΩΣ' ,'85300');
  OK
insert  into test.geo_dim2 (country_iso_a2, city_txt, zip_code) values ('GR','Κως' ,'85300');

select geo_sk, country_iso_a2, city_txt, zip_code from test.geo_dim2 GEO where GEO.COUNTRY_ISO_A2='GR' and GEO.ZIP_CODE='85300' AND GEO.CITY_TXT='ΚΩΣ'
  returns 1 row
select geo_sk, country_iso_a2, city_txt, zip_code from test.geo_dim2 GEO where GEO.COUNTRY_ISO_A2='GR' and GEO.ZIP_CODE='85300' AND GEO.CITY_TXT='Κως'
  returns 0 row   <<<<===================
  the process discussed earlier is doing an
  insert into target
  select from staging
  where staging column part of the key not in (select column part of the key from target table)
select geo_sk, country_iso_a2, city_txt, zip_code from test.geo_dim2 GEO where GEO.COUNTRY_ISO_A2='BE' and GEO.ZIP_CODE='8500' AND GEO.CITY_TXT='ΚORTRIJK'
  returns 1 row
select geo_sk, country_iso_a2, city_txt, zip_code from test.geo_dim2 GEO where GEO.COUNTRY_ISO_A2='BE' and GEO.ZIP_CODE='8500' AND GEO.CITY_TXT='Κortrijk'
  returns 1 row
Nevertheless, I still do not know why tests on another Teradata box returned 1 row in all case
and 'help session' cmd on both machines return the same setup
?
