GUI_DOWNLOAD problem in unicode system

Question

Hi Guru's,
I am facing one prolem in gui_download. we are doing unicode remediation in one report. In the program  one internal table declared as of type c with length 255 and data filled into the internal table by importing the data ifrom cluster. After  that this internal table  used  by ws_download function moduel with  file type as BIN to download it  in word doc file. We replaced the function module with gui_download. It is working fine in non-unicode system but it is not downloading properly in the unicode system.
i am unable to find what is the cause.. I tried with different different codepages giving in run time..it is not solving my problem.

Hi Clemens.
I replaced the ws_download function module with gui_download.
here is my code
Earlier before 6.0 code as follows
CALL FUNCTION 'WS_DOWNLOAD'
   EXPORTING
     bin_filesize            = data_len
     filename                = p_file
     filetype                = 'BIN'
   TABLES
     data_tab                = data_tab
   EXCEPTIONS
     file_open_error         = 1
     file_write_error        = 2
     invalid_filesize        = 3
     invalid_table_width     = 4
     invalid_type            = 5
     no_batch                = 6
     unknown_error           = 7
     gui_refuse_filetransfer = 8
     OTHERS                  = 9.
IF sy-subrc <> 0 AND no_error_dlg = space.
   MESSAGE i002(sy) WITH text-i03.    "FILE OPEN ERROR
ENDIF.
Replaced above with following code
  DATA:lv_fname TYPE string,
       lv_ftype(10) VALUE 'BIN',
       lv_codepage type abap_encod VALUE '4102'.
CALL METHOD cl_gui_frontend_services=>gui_download
    EXPORTING
      bin_filesize            = data_len
      filename                = lv_fname
      filetype                = lv_ftype
      codepage                = lv_codepage
    CHANGING
      data_tab                = data_tab
    EXCEPTIONS
      file_write_error        = 1
      no_batch                = 2
      gui_refuse_filetransfer = 3
      invalid_type            = 4
      no_authority            = 5
      unknown_error           = 6
      header_not_allowed      = 7
      separator_not_allowed   = 8
      filesize_not_allowed    = 9
      header_too_long         = 10
      dp_error_create         = 11
      dp_error_send           = 12
      dp_error_write          = 13
      unknown_dp_error        = 14
      access_denied           = 15
      dp_out_of_memory        = 16
      disk_full               = 17
      dp_timeout              = 18
      file_not_found          = 19
      dataprovider_exception  = 20
      control_flush_error     = 21
      not_supported_by_gui    = 22
      error_no_gui            = 23
      OTHERS                  = 24.
  IF sy-subrc <> 0 AND no_error_dlg = space.
    MESSAGE i002(sy) WITH text-i03.    "FILE OPEN ERROR
  ENDIF.
I tried with all othr code pages also like 4110/4103/1110/1100/1102. It is not working,
It is giving problem in unicode system. File is downloading.but not properly..
and when i am opening the word file it is asking me select encoding type to make document readble along with the  available text encoding formats.
Please help me..
Thanks & Regards,
