Lets you specify a specific output encoding to be used to write files. Enabling the check box causes the selected encoding to be forced for newly formatted files. You can either choose from one of the platform supported encodings or specify a specific encoding yourself.
When left disabled, the behavior depends on the used Plug-in. When using one of the IDE Plug-ins, the file encoding as specified in the IDE would be used. But the Ant, Console or Maven Plug-ins would use the platform default encoding instead.
Since 1.9.1
The Non-IDE Plug-ins allow you to control input and output encoding via configuration attributes/options directly. Please refer to the documentation of the individual Plug-ins for more information.
