[Rd] wchar and wstring.

Hello all, I am writing an R interface to some C++ files which make use of std::wstring classes for internationalization. Previously (when I wanted to make R strings from C++ std::strings), I would do something like this to construct a string in R from the results of the parse.

SET_VECTOR_ELT(vals, i++, mkString(header.GetHeader().c_str()));

However, now the call header.GetHeader().c_str() returns a pointer to an array of wchar_t's. I was going to use
wcstombs() to convert the wchar_t* to char*, but I wanted to see if there was a similar function in R for the mkString function which I had
initially used which deals with wchar_ts as opposed to chars. Also, since I have no experience with the wctombs() function I wanted to ask if anyone knew if this will handle the internationilzation issues from within R.

As always thank you for the help. jim
