Japanese font cannot display

Dear all,

I have a problem about character encoding(I think).

The problem is:
I have crated the execute prpt component in CDE dashboard and it can display japanese words on browser.(Please refer to the attached img1.jpg)
but after I download this data as CSV, and open on browser, it cannot display japanese words.(Please refer to the attached img2.jpg)

Could any one please guide me how can I do to be available japanese word when open with excel????

Thanks all..
