Note that the values assigned to parameters often need to be quoted to prevent shell expansion. Because Kurator-Akka interprets parameter values as YAML (or JSON) strings, so that lists and mappings may be provided as parameter values, quotes can be required to prevent interpretation as YAML as well. Using a pair of double quotes nested within a pair of single quotes can be the safest approach. For example, to use a question mark as the emphasis you will get an error unless you quote the ? in this manner (? surrounded by both double and single quotes):
$ kurator-akka -f hello_emphasized.yaml -p greeting=Goodbye -p emphasis='"?"'GoodybeGoodbye?$
