A small update to the above listed issue is that, we are using
Oracle 11.1.0.6.0 with character set (WE8ISO8859P1) and it belongs Spanish character set :

And the output of

select * from NLS_DATABASE_PARAMETERS;

PARAMETER                      VALUE
------------------------------ ----------------------------------------
NLS_LANGUAGE                   AMERICAN
NLS_TERRITORY                  AMERICA
NLS_CURRENCY                   $
NLS_ISO_CURRENCY               AMERICA
NLS_NUMERIC_CHARACTERS         .,
NLS_CHARACTERSET               WE8ISO8859P1
NLS_CALENDAR                   GREGORIAN
NLS_DATE_FORMAT                DD-MON-RR
NLS_DATE_LANGUAGE              AMERICAN
NLS_SORT                       BINARY

PARAMETER                      VALUE
------------------------------ ----------------------------------------
NLS_TIMESTAMP_FORMAT           DD-MON-RR HH.MI.SSXFF AM

NLS_NCHAR_CONV_EXCP            FALSE
NLS_NCHAR_CHARACTERSET         AL16UTF16
NLS_RDBMS_VERSION              11.1.0.6.0

We are suspecting, the problem could be because of the character set used by the oracle. Can anybody please help me on this?
Thanks in advance
