Too bad!
Setting the charset explicity in the Jasper compiled servlet breaks IE for
image/svg+xml content. It seems that Microsoft does not properly recognize
the contentType header so that for example running the resulting servlet
thus:
http://localhost:8080/foo/servlet/test?dummy=.svg will work but running it
properly thus: http://localhost:8080/foo/servlet/test will not work?
Obviously trying to fool IE with a dummy appended parameter won't help with
actual .jsp pages.
Tomcat 4.0 and below did not explicitly set the charset unless asked to, so
it works fine.
Perhaps there is a work around short of modifying the Jasper compiler?

The JSP spec states that the default character encoding, unless you
specify otherwise (on a "contentType" or "pageEncoding" attribute on the
<%@ page %> directive) must be ISO-8859-1.
