How about add a sample to this project?

When I create a project try to run this engine, I found that there are some mistake? e.g., there is no implementation of function "static std::string convertNonUtfString(const std::string &str);" I am a new guy to this, I want to do something. So I think if there have a sample code in this project will be cool, and people who interested will be easy to find some bugs.
