Commented Unassigned: Support for unicode [111]

I have non latin characters in my tests names and Chutzpah displays them wrong. Output from phantomjs.exe is correct (in utf-8) and simple adding:

```
p.StartInfo.StandardOutputEncoding = new UTF8Encoding();
```

in RunExecutableAndProcessOutput solves problem for me.
Comments: That is a nice simple fix. I will test and if all looks good will add for the 2.4 release
