Yes please! This sounds roughly like the solution I'd been imagining
where, for instance, boost::filesystem::path has string and wstring
contructors that work as they do now but also has path(utf8_string)
constructors that must be called like this:
std::string system_encoded_text = some_non_utf8_aware_library_call();
The utf8_string class would do the conversion from the system encoding.
