Test: UTF-8 vs latin-1 regression

We need to determine wether or not Riak 1.4's app.config and vm.args file could accept UTF-8 values or if they are restricted to latin-1. For example, multi backend bucket names.

If riak 1.4 can accept UTF-8 values, cuttlefish needs to be able to as well. If they can't , then it's desirable for cuttlefish to be able to detect non latin1 files and print an error message, but that might be a 2.0.1 fix.
