Problem with German Umlauts

Hello Community,

two days ago i've installad the abap2xlsx-tool and i have tested some demo-reports.

The Tool is great and I want to use it for some problems with my own zreports.

My mainproblem at the moment:

I can't use the generated CSV-File with customer data because the german umlauts looks horrible.

I've used the code from ZDEMO_EXCEL28.

Create the Excel-Object and used the methods from zcl_excel_writer_csv

In my opinion the FM SCMS_XSTRING_TO_BINARY is the problem.

" Convert to binary
     CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
       EXPORTING
         buffer        = lv_file
       IMPORTING
         output_length = lv_bytecount
       TABLES
         binary_tab    = lt_file_tab.

     lv_full_path = ifile.

*    " Save the file
     CALL METHOD cl_gui_frontend_services=>gui_download
       EXPORTING
         bin_filesize              = lv_bytecount
         filename                  = lv_full_path
         filetype                  = 'BIN'
*    append                    = SPACE
*    write_field_separator     = SPACE
*    header                    = '00'
*    trunc_trailing_blanks     = SPACE
*    write_lf                  = 'X'
*    col_select                = SPACE
*    col_select_mask           = SPACE
*    dat_mode                  = SPACE
*    confirm_overwrite         = SPACE
*    no_auth_check             = SPACE
         codepage                  = '4110'               "UTF-8
*    ignore_cerr               = ABAP_TRUE
*    replacement               = '#'
*    write_bom                 = SPACE
*    trunc_trailing_blanks_eol = 'X'
*    wk1_n_format              = SPACE
*    wk1_n_size                = SPACE
*    wk1_t_format              = SPACE
*    wk1_t_size                = SPACE
*    show_transfer_status      = 'X'
*    fieldnames                =
*    write_lf_after_last_line  = 'X'
*    virus_scan_profile        = '/SCET/GUI_DOWNLOAD'
*  IMPORTING
*    filelength                =
       CHANGING
         data_tab                  = lt_file_tab
       EXCEPTIONS
         file_write_error          = 1
         no_batch                  = 2

Codepage-Statemant won't change anything in my resultfile.

In my old program i create a string table and call ....GUI_DOWNLOAD with filetype 'ASC' and it looks fine.

CALL METHOD cl_gui_frontend_services=>gui_download
       EXPORTING
*      bin_filesize              =
          filename                  = ifile
          filetype                  = 'ASC'
*      append                    = SPACE
          write_field_separator     = space
*      header                    = '00'
*      trunc_trailing_blanks     = SPACE
          write_lf                  = 'X'
*      col_select                = SPACE
*      col_select_mask           = SPACE
*      dat_mode                  = SPACE
          confirm_overwrite         = space
*      no_auth_check             = SPACE
*       codepage                  = '1160'
*      ignore_cerr               = ABAP_TRUE
*      replacement               = '#'
*      write_bom                 = SPACE
*      trunc_trailing_blanks_eol = 'X'
*      wk1_n_format              = SPACE
*      wk1_n_size                = SPACE
*      wk1_t_format              = SPACE
*      wk1_t_size                = SPACE
*      show_transfer_status      = 'X'
*    IMPORTING
*      filelength                =
       CHANGING
         data_tab                  = ithsexp

Can anybody help me with my problem or is it not possible to do it with the functions from ABAP2XLSX.

Thanks.
