Also, is there any use in trying to get the difference into the type system, e.g. by using some kind of wrapper over std::string that gives it a distinct "utf-8" type?
The system I'm now using for my programs might interest you.
I have four classes: ascii_t, utf8_t, utf16_t, and utf32_t.

There are some parts of the code that could use polishing, but I like the overall design, and I'm finding it pretty easy to work with. Anyone interested in seeing the code?
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(); filesystem::path utf8_file_path(boost::utf8_string(system_encoded_text)); The utf8_string class would do the conversion from the system encoding.
