The process of using UTF-8 may requires requires adjustments to one or more the following layers,
- Set Files and Workspace to UTF-8
- Servlet Container
- Server Operating System
- Server Database if one is being used
Following this tutorial it will be clearly evident if UTF-8 is working. As such, we will stop at each layer to see the results of our changes. It may be the case that the other layers already default to UTF-8.
