Excel Download (chinese Charaters) in Webdynpro Java

Hi Experts,

I have implemented webdynpro Java program to download the data from Webdynpro Java table to MS Excel, but it is unable to download the Chinese Characters from the Webdynpro app Table to Excel? Wondering if there is any Unicode issue (english-english download) is working fine.

Currently we are on WAS 7.0,

NWDS Version: 7.0.18

Netweaver 04s.

Would really appreciate if you could let me know if there is any Java api / Java class in any package which does not have Unicode limitation, and can handle Chinese Characters?

Currently i am using

com.sap.tc.webdynpro.progmodel.api.IWDModifiableBinaryType;

com.sap.tc.webdynpro.services.sal.url.api.WDWebResourceType;

Awaiting for your reply.

Thanks in advance.
