On Windows, mvn spring-boot:run passes the stdout/stderr encoding properties to the
forked application JVM through JAVA_TOOL_OPTIONS, but not file.encoding (it would
change how Maven reads sources). On JDK 8-17, logback / log4j2 console appenders
encode with the default charset (GBK on Chinese Windows) and ignore stdout.encoding,
so Chinese log lines showed as U+FFFD in the UTF-8 Run console.
For a Maven launch with a spring-boot:run goal and a UTF-8 console, add
-Dfile.encoding=UTF-8 to -Dspring-boot.run.jvmArguments, merged into the user's
VM options. It reaches only the forked JVM; Maven's own JVM is unchanged. A
file.encoding the user set (in jvmArguments or JAVA_TOOL_OPTIONS) wins.
