Generate a Quarkus application from https://code.quarkus.redhat.com/ , e.g check Camel Core [camel-quarkus-core] , then click on "Generate your application" button Download the source zip, unzip locally Do podman build using command such as: podman build -f Dockerfile.jvm -t code-with-quarkus-jvm then run it using: podman run -it localhost/code-with-quarkus-jvm /bin/bash In the container, execute java -XshowSettings, and the output showing Property settings: file.encoding = ANSI_X3.4-1968 expected: Property settings: file.encoding = UTF-8 This cause an issue with special characters. The Dockerfile.jvm has the following conent: FROM registry.access.redhat.com/ubi8/openjdk-11:1.11 ENV LANG= 'en_US.UTF-8' LANGUAGE= 'en_US:en' # We make four distinct layers so if there are application changes the library layers can be re-used COPY --chown=185 target/quarkus-app/lib/ /deployments/lib/ COPY --chown=185 target/quarkus-app/*.jar /deployments/ COPY --chown=185 target/quarkus-app/app/ /deployments/app/ COPY --chown=185 target/quarkus-app/quarkus/ /deployments/quarkus/ EXPOSE 8080 USER 185 ENV AB_JOLOKIA_OFF="" ENV JAVA_OPTS= "-Dquarkus.http.host=0.0.0.0 -Djava.util.logging.manager=org.jboss.logmanager.LogManager" ENV JAVA_APP_JAR= "/deployments/quarkus-run.jar" if the line "ENV LANG='en_US.UTF-8' LANGUAGE='en_US:en'" is commented out, then the container has the correct file.encoding as it is taken from the image registry.access.redhat.com/ubi8/openjdk-11:1.11. Is it possible to change the way the application is generated?
