Encoding issues

[wush978]

Dear all,

First of all, I want to thank for your great work of swirl and swirlify.

I want to use swirl in a workshop for introducing R in Chinese, but I have an encoding issue. The yaml::yaml.load_file only parse UTF-8 encoded document and the rendering in windows is failed.

The following images show the failure with the swirl installed from github:

Inspired by vubiostat/r-yaml#6, I mark the Encoding to the raw_yaml in parse_content.yaml master...wush978:master. The rendering of the Chinese text becomes normal:

Could I give you a PR to resolve this issue?

Best,
Wush

Dear @seankross ,

You could check #300 for the proposed solution. The wrap_encoding recursively mark the encoding of all strings returned from yaml parser. I like to hear any comment from you about this approach.

However, I just notice that the wrap_encoding will trigger error when the raw_yaml contains non-list and non-character object. It is easy to fix this, but I think it's better do it after hearing your feedback.

And it seems that the test cases does not detect this error ( #300 passes the CI ). I could send a PR to detect such kind of error in another PR if you like.
