How to read a Unicode text file in a non-unicode SAP system

Question

I'm currently has a text file which is saved as UTF-8 format. And inside this file has Thai characters.
However, my SAP system is a non-unicode system.
When I use the code
open dataset DSN for output in TEXT MODE encoding UTF-8
the thai characters become some funny characters.
How can I solve this in the ABAP program without changing the system from non-unicode to unicode system?

Hi Eswar,
   How can I check whether the code page for THAI already installed or not in SAP system?
   Here is the code I use to test to read a file that saved as UTF-8.
DATA: l_filepath         TYPE string.
DATA : BEGIN OF l_filepath_str OCCURS 0,
             comm(1000)  TYPE c,
           END OF l_filepath_str.
DATA: l_datasetsucc LIKE rlgrap-filename.
l_filepath = '/BAAC/Files/APP_.txt'.
OPEN DATASET l_filepath FOR INPUT IN TEXT MODE ENCODING UTF-8.
IF sy-subrc EQ 0.
  DO.
    CLEAR l_filepath_str.
    READ DATASET l_filepath INTO l_filepath_str.
    IF sy-subrc EQ 0.
      APPEND l_filepath_str.
    ELSE.
      EXIT.
    ENDIF.
  ENDDO.
ELSE.
  WRITE:/ 'Error reading from file:', sy-subrc.
ENDIF.
CLOSE DATASET l_filepath.
LOOP AT l_filepath_str.
  WRITE: / l_filepath_str-comm.
ENDLOOP.
    It returns me a runtime error. Any idea?
