How to set the JVM charset on the command line?

问题

What's the command to set the JVM's character set?

(Also, what's the command to view the current JVM's character set, so I know how to reset it back to default after I'm done)

Thanks,

回答1:

java strings are always utf-16 internally (javadoc link), but you can use -Dfile.encoding=UTF-8 to facilitate reading files with a default charset.

Just ensure java has access to that fileset when you set it or it won't start.

回答2:

java.nio.charset.Charset.defaultCharset() Will get you the JVM's default charset.
