Language Conversion : Getting junk character in excel file

Hi Experts,

I am getting one issue while sending data in form of email. I have certain data in ALV output & I am sending that data through email using one custom function module.

This function module is sending data as ZIPPED file. If we open the ZIPPED file it is displaying file as .XLS file.

Now the issue is that material description is maintained DE language & in output that description is coming proper i.e. whatever maintained in DE language.

But when ever I am receiving email, the DE text gets converted to zunk character. While debugging I found that data is properly populated in internal table prior to using Custom FM.

Can anybody will suggest how I can resolve it?

Thanks,

Neha
