Different filetypes from source

Question

Hi, I want to know what I can do if I'm receiveng txt files that has to been loaded to a Oracle's DB.
When analyzing the data we found that there were rows that seemed to be empty('') using TOAD but then we changed to SQL -Developer and we could see the info on those rows.
So we went to our source files and found that the file types were "Little-endian UTF-16 Unicode character data, with CRLF line terminators" and we were expecting to receive only UTF-8 files, so , is there a way I could identify what kind of file am I receiveing and write some code to process every file according to its type?
I want to know if I can do this or I should work it into small processes like first verify the type and if it is different make a conversion and then load it.
What do you think?
Any advice will be appreciated.

Version:
Oracle Enterprise 11g running on RAC (4 nodes)
SQL:
SELECT SUM (TRI.IMPORTE) IMPORTE, TRA.ID_PUESTO
FROM RAPIPAGO.RP_TRANSACCION_ITEM@LINK_OL TRI,
(SELECT TR.ID_TRANSACCION TRANSACCION,
PU.PUESTO,
PU.ID_PUESTO,
TR.TIPO_OPERACION
FROM RP_PUESTO PU
INNER JOIN
RAPIPAGO.RP_TRANSACCION@LINK_OL TR
ON ( PU.ID_PUESTO = TR.ID_PUESTO
AND TR.IS_DELETED = 'N'
AND TR.ID_ENV = 'RPPRI')
WHERE TR.ID_OPERACION_CAJA IS NULL
AND PU.ID_AGENTE_SUCURSAL = '28966273343800000332'
AND PU.IS_DELETED = 'N'
AND PU.ID_ENV = 'RPPRI'
AND TR.TIPO_OPERACION = 3) TRA
WHERE TRA.TRANSACCION = TRI.ID_TRANSACCION
AND TRI.IS_DELETED = 'N'
AND TRI.ID_ENV = 'RPPRI'
GROUP BY TRA.ID_PUESTO
Explain plan:
It doesn't show, obviously, the resolution of the remote select, but neither a problem in the access. In fact, the query goes fine from TOAD.
Thanks, and sorry for the missing details.
