unmappable character (0xF3) for encoding UTF-8

[myxor]

We have some code which contains special characters in the tests and i see a lot of errors like this:

failed to parse [filename redacted] with reason: unmappable character (0xF3) for encoding UTF-8

@myxor
I tried to reproduce that issue using the following sample code:

class A {
        public static void main(String[] args) {
                int ó = 1;
        }
}

For me that works in both the current release version and the current develop version. This might be an issue dependent on the operating system though. Can you either send me an example code, that fails for you or try the develop version?
