Packaged .exe contains mangled copyright symbol

In the build script:

compose.desktop {
    application {
        mainClass = "garden.ephemeral.calculator.MainKt"
        // ...
        nativeDistributions {
            // ...
            copyright = "Copyright © 2022 $vendor"

            windows {
                upgradeUuid = "3e9ee76f-453c-4819-9371-41745b72b8cc"
                menuGroup = packageName
                iconFile.set(file("src/installers/AppIcon.ico"))
            }
            // ...
        }
    }
}

The resulting .app file has the © replaced by Å©:

Compared to an executable made by MS:

Most likely, jpackage is being run with Windows' default encoding and has to be set to UTF-8 so that it doesn't mangle the input?

Versions in play:

• JDK 17.0.1
• Gradle 7.5.1
• Compose Gradle Plugin 1.1.0

It doesn't seem to say anything about this in the jpackage docs at all, but I'm guessing that adding -J-Dfile.encoding=UTF-8 might work for this executable too, as it commonly does work for other java tools...

It would have to go somewhere around here:

https://github.com/JetBrains/compose-jb/blob/master/gradle-plugins/compose/src/main/kotlin/org/jetbrains/compose/desktop/application/tasks/AbstractJvmToolOperationTask.kt#L71

And for obvious reasons can't be inside the argsFile.
