If you are getting Invalid UTF-8 middle/second byte or other parsing errors within your JVM, just know

that  :

"The default charset is determined during virtual-machine startup and typically depends upon the locale and charset being used by the underlying operating system."

This is an official excerpt from  :

https://docs.oracle.com/javase/8/docs/api/java/nio/charset/Charset.html

Other sources that just relate to how to determine or set it up:

https://docs.oracle.com/javaee/7/tutorial/webi18n004.htm

Now, how do you know what character set is your JVM defaulting to?

In debug, try to execute the following command:

java.nio.charset.Charset.defaultCharset()

You will get one of the charset listed here (most popular being  iso-8859-1):

https://docs.oracle.com/javase/7/docs/technotes/guides/intl/encoding.doc.html

To make sure you have a broad encoding character set, solve this issue by overriding your system charset by starting the jvm with this option:

-Dfile.encoding=UTF-8
