How to use Rcpp::wrap() to convert C++ data types?

1. tiny-utf8

   1 2 547 4.3 C++

   Unicode (UTF-8) capable std::string

   

   I've recently been trying to use the tiny-utf8 library in Rcpp in order to handle unicode, but I am having serious issues trying to understand how the "wrap" part of it works. For the "as" part, I've received some help on Stack Overflow, which works great, but without a wrap(), it seems that I cannot convert the data type into those of Rcpp. I've been reading this post and trying to replicate it, but with utter failure after long hours, due likely to a lack of knowledge in C++ templates. Could someone give some pointers as to how I might go about doing this? I am at the end of my wits at this point.
