It is not exactly clear what the problem is from your description. I guess you are talking about an application problem like some characters getting display incorrectly in web pages or a Swing UI view.
If so you are using files in an encoding other than the encoding on your target platform. Say ISO-8859-1 vs. UTF-8. From my experience it is always best to use UTF-8 everywhere (or ASCII everywhere - which normally isn't a viable option in internationalized apps). But to be able to help you would have to be a bit more specific about your problem.
Or are you talking about a problem with the administration of your modules (eg deploying them and how they are named in the admin console)?
