incompatible character encodings: UTF-8 and ASCII-8BIT when trying to match systemd units status

[scalp42]

Hi folks,

I noticed #146 was open but I'm not sure if it's related in some way.

Assuming a default CentOS 7 box for example with dnsmasq installed:

$> yum -y install dnsmasq

And the following test:

describe command('service dnsmasq status') do
  its('stdout') { should match(/\/usr\/sbin\/dnsmasq -k/) }
end

Kitchen will fail with error:

>>>>>> ------Exception-------
>>>>>> Class: Kitchen::ActionFailed
>>>>>> Message: 1 actions failed.
>>>>>>     Failed to complete #verify action: [incompatible character encodings: UTF-8 and ASCII-8BIT] on default-centos-7
>>>>>> ----------------------
>>>>>> Please see .kitchen/logs/kitchen.log for more details
>>>>>> Also try running `kitchen diagnose --all` for configuration

Here's a gist to the full log: https://gist.github.com/scalp42/3d788f09510a3c8eb6681f9de20e1f6c

ChefDK versions:

Chef Development Kit Version: 2.5.3
chef-client version: 13.8.5
delivery version: master (73ebb72a6c42b3d2ff5370c476be800fee7e5427)
berks version: 6.3.1
kitchen version: 1.20.0
inspec version: 1.51.21

I'm assuming the error comes from the dot in the status output:

[root@default-centos-7 ~]# service dnsmasq status
