Cl_gui_frontend_services= gui_download - issue with german special char

Question

Hello,
we are using cl_gui_frontend_services=>gui_download to create from an itab an excel file.
We face the issue that in this excel file german special characters like Ä, Ü, Ö, ß are not displayed correctly.
I think we need to use a different codepage. But which one?
could you please give us a short coding example how to call cl_gui_frontend_services=>gui_download.
Thanks a lot
Kind regards
Manfred

Hi,
Check the system is unicode or non-unicode . Codepage for Unicode system is ' 4102' and non-unicode is '1100'.
Below are the sample code for the GUI_download with Class.
DATA:  l_filename    TYPE string,
       l_filen       TYPE string,
       l_path        TYPE string,
       l_fullpath    TYPE string,
       l_usr_act     TYPE I.
l_filename = SPACE.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
  EXPORTING
    DEFAULT_FILE_NAME    = l_filename
  CHANGING
    FILENAME             = l_filen
    PATH                 = l_path
    FULLPATH             = l_fullpath
    USER_ACTION          = l_usr_act
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2     
    NOT_SUPPORTED_BY_GUI = 3
    others               = 4.
IF sy-subrc = 0
      AND l_usr_act <>
      CL_GUI_FRONTEND_SERVICES=>ACTION_CANCEL.
CALL FUNCTION 'GUI_DOWNLOAD'
  EXPORTING
    FILENAME                        = l_fullpath
   FILETYPE                        = 'DAT'
  TABLES
    DATA_TAB                        = T_DOWNL
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
   OTHERS                          = 22.
IF SY-SUBRC <> 0.
   MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
ENDIF.
