How to set the JVM charset on the command line?

Question

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,

Solution 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.

Solution 2

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