gvSIG-Desktop 1.9. User manual
This option can be accessed by opening the Window > Preferences menu and then selecting DBF default encoding.
gvSIG will use the selected encoding as the default when adding a .dbf file to a project, and will also use it when exporting a table that uses a specific encoding.
The export of a table might not be correct if the character encoding is incorrectly configured in the gvSIG preferences.
