------------------------------------------------------------------
Note: Servlet Spec 5.4 says that "If the servlet does not specify a character
encoding before the getWriter method of the ServletResponse interface is called
or the response is committed, the default ISO-8859-1 is used."
I'm unclear why, sometimes, it worked before, but as there doesn't seem to be
any other mechanism in Mifos to force (JSP) output to UTF-8, my best guess is
that "by chance it sometimes worked before" - and that the "solution" is to "do
something explicit to force UTF-8" in responses.
A Servlet Filter to force the encoding to UTF-8 actually was a good idea to
start with. There were two main problems with it though:
1. Struts uses RequestDispatcher.forward() which, under Jetty 7.3.0 at least,
cleared the encoding set by the filter and made the JSPs be served with the
default ISO-8859-1 again. Solved this via <dispatcher>FORWARD</dispatcher> in
the <filter-mapping> (I've set all 5 types, just to be safe).
2. Spring's org.springframework.web.filter.CharacterEncodingFilter actually
won't work because (I think) their OncePerRequestFilter; I suspect this may
turn out to be a subtle Spring bug, I've created
https://jira.springsource.org/browse/SPR-8019 for follow up on a separate
thread; solved short-term with our own
org.mifos.servlet.filters.CharacterEncodingFilter.

> Jetty is incorrectly setting a non-UTF-8 character set for Struts/JSP pages.
> I'm using Google Chrome's developer tools to view the response headers, but
> other software (ie: firefox plugins) can also be used to view response
> headers.
> h1. Expected
> {noformat}Content-Type:text/html;charset=UTF-8{noformat}
> SpringMVC/ftl pages work. For example: http://ci.mifos.org:8118/mifos/
> h1. Actual
> {noformat}Content-Type:text/html;charset=ISO-8859-1{noformat}
