I was trying to use your code at this link....

I was able to succesfully get the Excel export function working but there are issues with the CSV I am still troubleshooting.
My issue is this though. I have a Gridview of both English and other foreign languages such as Japanese and Thai. The foreign Asian languages do not export properly using your code. Europena languages such as Spanish, French and Italian have no problem.
Do you have a fix to support the Asian languages?
thank you.
