I got a similar issue under JBoss using Displaytag 1.2 picked from a Stripes MVC application.

When the database (MySQL) was giving strings containing Scandinavian language characters encoded in UTF-8, then the CSV and Excel exporting of those tables was corrupted i.e. the downloaded file contained no data or a small amount of useless corrupted data.

I think the main issue, data related, was regarding Finnish characters' encodings which are in ISO-8859-1 but not in UTF-8 (cfr. http://en.wikipedia.org/wiki/ISO/IEC_8859-1).

The fix that is working for me was to:

1. adding this to the Stripes Action Bean:

   getContext().getResponse().setCharacterEncoding("UTF-8");
   getContext().getResponse().setContentType("application/vnd.ms-excel;charset=UTF-8");
   

2. adding this to the corresponding JSP:

   <%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
   

After this I am succesfully able to download CSV and Excel files from a Displaytag table containing data encoded with UTF-8 characters from Scandinavian languages.

After searching i found solution for this case: You should Add
response.setContentType("application/vnd.ms-excel;charset=Cp1256");
instead of:
request.setCharacterEncoding("UTF-8");
in <% DisplayProperty .....> line

for benefit

We are using DisplayTag 1.1.1 and we had a problem with special character encoding (UTF-8) in Excel/CSV export. After some search's we were able to fix the issue by adding BOM before export string to writeExport() in TableTag.java class.

Ex:

JspWriter lOut = pageContext.getOut();

...

lOut.write('\ufeff');

lOut.write(pExportString);

This works well (display special characters correctly) except in xls output, all data displayed in one cell in Excel 2010 although CSV output displayed correctly. \t - TAB separator didn't work after adding BOM. But if we replace \t with Comma(,), it works as expected in Excel 2010.
