Description

When trying to declare the return type of a method having non-ASCII characters, such as in the following example:

InternationalizationTest.groovy

@groovy.transform.ThreadInterrupt
@groovy.transform.TypeChecked

public class 对象 {

public 对象 get对象()
{
    return new 对象()
}

}

def myVar = new 对象()

the compilation fails with the message:

unexpected token: public at line: 6, column: 1

Those characters are valid according to the official documentation and using them in other places such as a class or variable declaration works as expected.
I'm attaching the example in order to provide an easy way to test the issue.
