I'm using hudson with Japanese environment.
When I show status monitor, I receive message with unreadable, grabled characters.

I think this is because HTTP response returns the content-type header as "ISO-8859-1" though html should be UTF-8.

The response header is following:
==================================================
Server: Winstone Servlet Engine v0.9.10
Content-Type: text/html;charset=ISO-8859-1
X-Powered-By: Servlet/2.5 (Winstone/0.9.10)
