[logback-user] Character encoding problem with ch.qos.logback.access.servlet.TeeFilter

After a long process of elimination, I've discovered that the TeeFilter
(ch.qos.logback.access.servlet.TeeFilter) is causing problems with page
Java: 1.7_0_51 (and 1.6.0_39).
At the top of my jsp pages I have this line:
<%@ page language="java" contentType="text/html; charset=UTF-8"
setting the character set to UTF-8. When I have the TeeFilter installed in
the web.xml, unicode characters do not encode correctly. The resulting
html page claimed to be UTF-8 in its header, but did not appear correctly
when interpreted as UTF-8 or iso-8859-1. (I don't know what encoding it
was actually using).
For now, my workaround is to remove the TeeFilter since my dependence on it
is very low, but I would like to be able to add it back if needed.
Another detail about this that confuses me even more, is that it would fail
100% of the time when tomcat was first started. But if I redeployed the
.war files, it would start working and the pages would be encoded
correctly. (This made tracking the problem down a much longer process).
Has anyone else run into this or is there a setting on the TeeFilter to
specify an encoding?
