Json serialization for Unicode

[naveensrinivasan]

This will fix the Unicode Json serialization bug #967.

When I was looking at the code I realized there was already a fix with a PR facebook-csharp-sdk/simple-json#66 .Reused the same code for this fix.

Sweet. :)

I'm hesitant to take this because SimpleJson.cs is a dependency we pull in from NuGet. Have you tried the latest version to see if it already has a fix?

If not, could you submit a PR upstream to https://github.com/facebook-csharp-sdk/simple-json?

I worry that the next time we upgrade, we'll break this. At least the unit test will catch it though. 😄

@haacked I looked for that first before making the change. https://github.com/facebook-csharp-sdk/simple-json hasn't been updated in the last 20 months. There is already a PR with this fix for the main repo which is still pending from April. That's the reason for making a change in this repo.

I understand your concerns. What do you want to do?

Ping @prabirshrestha and ask what he's been up to? 😉

Ok, as long as the PR is upstream, I'll take this one.
