JetBrains: Fix Windows encoding issue

Created by: philipp-spiess

Closes #38218 (closed)

Apparently using new String(byte[]) without specifying a charset will default to using the default charset which can be different across operating systems and JVM version.

To fix the issue we only have to tell the JVM that the byte array is UTF-8 encoded.
