Configuring a Project
To configure a project to support UTF-8:
On JDeveloper, right-click the project folder that will include non-English data, and then select Project Properties from the context menu.
In the navigation pane on Project Properties, select Compiler.
In the Compiler pane, select UTF-8 from the Character Encoding drop-down list box.
Click OK.
Only the selected project shows UTF-8 as the value for the Character Encoding field.
Restart JDeveloper.
You can insert non-English data and run your project.
