内表下载至excel，中文变成#号

我们是英文系统，在我调用ws_download和gui_download的时候内表的中文在excel里都变成了#

尝试增加列宽行高，不行
更改Codepage参数，乱码

最后尝试一个很好用的的函数，解决了这个问题，而且还不会有弹窗

PARAMETERS: p_path  LIKE rlgrap-filename.
"文件名.xlsx  就不会有弹窗
  CALL FUNCTION 'SAP_CONVERT_TO_XLS_FORMAT'
    EXPORTING
*     I_FIELD_SEPERATOR          =
      i_line_header  = 'X'
      i_filename     = p_path
*     I_APPL_KEEP    = ' '
    TABLES
      i_tab_sap_data = gt_tab
* CHANGING
*     I_TAB_CONVERTED_DATA       =
* EXCEPTIONS
*     CONVERSION_FAILED          = 1
*     OTHERS         = 2
    .
  IF sy-subrc <> 0.
* Implement suitable error handling here
  ELSE.
    MESSAGE 'successful!' TYPE 'S'.
  ENDIF.

附上文件路径的F4帮助
