    After being yesterday all afternoon looking for the reason why the data obtained from a database sometimes appeared with some characters "changed" and other times not, I have given when the reason is as follows:

    If I execute the .jar directly the result is different to if the program is launched directly from the programming IDE.

    See the attached image to better understand the problem.

    Can I do something so that when executing from the IDE it behaves in the same way as when I execute the .jar directly?

    You could try
    #VirtualMachineArgs: -Dfile.encoding="UTF-8"

    ¿Where do I have to put it? ¿ Like a param of the .jar file ?

    What I really need is that when running from the IDE, the application works as when I execute the .jar directly and not the other way round.

    The data source is a Firebird DB that is not in UTF-8.

    This will not help. The parameter will not be included in the executable jar.

    You have a few options:
    1. Run the jar with a batch file and add this parameter: -Dfile.encoding="UTF-8"
    2. Convert it to an executable with launch4j and add the parameter: https://www.b4x.com/android/forum/threads/create-windows-native-executables-exe-files.35863/#content
    3. Create a full packager and add the parameter to the installer.
