After outfile is set to Chinese, although the exe is successfully created, it cannot be run.

[koreQAQ]

This is my gradle task

tasks.register<edu.sc.seis.launch4j.tasks.Launch4jLibraryTask>("generateExe") {
    dependsOn("jar")
    jreMaxVersion.set("1.8.1")
    jreMinVersion.set("1.8")
    bundledJrePath.set("jre")
    outfile.set("口袋方舟" + ".exe")
    mainClassName.set("com.metaverse.app.LauncherApplication")
    fileDescription.set("The lightning fast implementation")
}

This is the result after running

I tried checking the XML and found gibberish

What makes me curious is that as long as the file name is changed to any English, the exe can run

@koreQAQ are you running the gradle (daemon) JVM with utf-8 file encoding and what JDK/Java version are you using?

How to determine the encoding format of the gradle daemon．
I opened my IDEA and set the encoding format in the lower right corner to UTF-8, but my Windows 10 system started with GBK encoding in Beta mode. Based on the above situation, creating exe is no longer garbled.
I use Java8 version.

In Jetbrains IDEs the mentioned statusbar menu changes the encoding of the currently opened file. To change the gradle daemon, add the line org.gradle.jvmargs='-Dfile.encoding=UTF-8' to the gradle.properties file in your project root. Then stop the daemon (./gradlew --stop) and run the createExecutables task again.
