Hi,

I am running an Rspec test case which takes in some json files and matches them against an expected output after being put through my filter.

However, I am getting an error during the validate\_valie phase where it is complaining that US-ASCII is being used, instead of UTF-8, even though US-ASCII is a subset of UTF-8.

Any suggestions as to how I can force the encoding?

Thanks

Below is the stack trace I am getting

```

Got this. The solution is to use the "magic\_encoding" gem
