After that convert a char in the string to a half byte. This should be at least not-worse than your version for small strings - there's no opportunity for the compiler to make a sub-optimal inlining decision on the string stream operators in particular, and (named) RVO will take care of eliding the copy from the return value to the caller's std::string hex. Since char* and w_char* are different types, the functions that process wide strings are different than the ones processing normal strings and have different names.
