Description
If I add a UTF-16 string, like the following, MethodMatcher prints it quoted:

$ ./bin/java -XX:CompileCommand=compileonly,����������::���������� -XX:+PrintCompilation -version
CompileCommand: compileonly \u041a\u043b\u0430\u0441\u0441.\u043c\u0435\u0442\u043e\u0434

I think we should print the same UTF string, because this is an output aimed for the end user, who will not see a class and method name in stdout in the case of quoted symbols.
