Applications started by Gradle (bootRun, run, custom JavaExec tasks) kept the
ANSI default charset (GBK on Chinese Windows, JDK 8-17) while the Run console
decodes UTF-8. Code that converts text with the default charset then breaks:
Nacos config with Chinese text fails to parse (MalformedInputException) and
logback/log4j2 console output is garbled.
For a UTF-8 console on Windows, a Gradle launch now gets an init script that
adds -Dfile.encoding=UTF-8 to each JavaExec task when it runs, unless the task
or JAVA_TOOL_OPTIONS already sets file.encoding. Gradle's own JVM and compiler
source encoding are unchanged. Maven and Gradle are told apart so the
spring-boot:run rewrite only applies to Maven.
