force data read from 'sysctl -a' into ASCSII

[lukebigum]

Avoids Puppet complaining about invalid Unicode. Bit of a hack, but gets around https://bugzilla.redhat.com/show_bug.cgi?id=1879868

Coverage increased (+0.07%) to 88.136% when pulling edb79e9 on lukebigum:unicode_fix into e58fc8e on hercules-team:master.

Thanks. It's better than nothing indeed. Are you able to provide tests for this?

[foxxx0]

Tested manually on a system that suffers frome the same issue and I can confirm that it works here.

I suppose the test should inject some sort of invalid utf8 sequences and expect not to contain them in the output lines? Or maybe put the code into its own method for easier testing and just mapping it to the sysctl -a lines array before iterating it?

[raphink]

Oh well, I'll just merge like this 🤷

[bastelfreak]

@raphink thanks for merging. could you push a new release?

[raphink]

Done
