I18N - sending unicode data to Excel from servlet displayed as "?"

Hi,

In my application we are export some unicode data to Microsoft Excel 2003 from servlet .

For that i am using the following code.

response.setHeader( "Content-Disposition", "attachment; filename=results.xls" );

response.setContentType( "text/xls" );

theHeader.append("\u30ec\u30dd\u30fc\u30c8 \u30bf\u30a4\u30c8\u30eb");

.

The above unicode data (japanese character) not displaying properly in Excel (display as "?"). other non unicode things are display properly.

can anyone advise me.
