Chris,

In any software using Hibernate with Envers, simply create a persisted field with this name: "aáçãéèíõÃÕÇñÑ", and then try to start it.

If you can't reproduce it, a test case will do no good. You probably have your platform's default charset setup such as it won't fail. See what I wrote above: "...the platform's default charset, ... may result in code that works on some platforms and fails on others..."

So you most likely need to change the default charset of your JVM to see the bug. See here:
