How to use gui_download 's filetype of 'bin'

Question

Hello,experts ,the detail of my problem as follows:
I use gui_download to download the invoice data :filetype is ASC,the download file is .txt file with tab as the field 's separator.
the internal table:i_khzl :DATA: BEGIN OF i_khzl OCCURS 0,        "ITAB OF HEAD INFO.
        fpdm(15),                      "invoice no
        tdh(15),
        khswdjh(15),                   "
        khmc type TEXT100,
       " khmc(100),                     "customer
        khdz(100),                     "
        khyh(100),                     
        bz(100),                       "
        qdhj(1),
        jmhj(1),
        fphm(18),                 
      END OF i_khzl.
but there is not  a Chinese characters like"燊" in the codepage 8400, which result in the customer name display as wrong ,the last byte is '?', and the I download the data using filetype of BIN ,the ? of customer name is gone,but the local file  .txt the format is wrong, which the interface of the invocie system can not confirmed.

THE CONTENT OF THE LOCAL TXT IS :
ASC:
0491052960          451281672481214     宜州市燊龙贸易有限责任公?                                         
BIN:0491052960                    451281672481214宜州市燊龙贸易有限责任公司                                                                         
the format of the two txt content is different, how to change the bin 's type to asc' type ?or how to use the gui_download function to solve the wrong display of the customer name?
pls help me ,
much appreciated.

Dear Pradeep,
Find the below link which explains a simple data download to excel from a table view.
www.sapt echnical.com/Tutorials/BSP/Excel/Index.htm
Try to avoid the way your using in the BSP application and it is abdicable to use the standard methods / class available like "cl_bsp_utility"
Hope this will be helpful.
