Defaults to false. Consul 1.0.3 fixed a potential security vulnerability where
malicious users could craft KV keys with unprintable chars that would confuse
operators using the CLI or UI into taking wrong actions. Users who had data
written in older versions of Consul that did not have this restriction will be
unable to delete those values by default in 1.0.3 or later. This setting
enables those users to _temporarily_ disable the filter such that delete
operations can work on those keys again to get back to a healthy state. It is
strongly recommended that this filter is not disabled permanently as it
exposes the original security vulnerability.
