That's why I think that the only sensible interpretation of paths coming from URLs is as UTF-8, and for this case, the default filesystem conversion isn't suitable.

Can you please submit a pull request showing me how route.cpp can be correctly implemented according to these semantics?

The usual approach is to put

boost::filesystem::path::imbue( std::locale( std::locale::classic(), new boost::filesystem::detail::utf8_codecvt_facet ) );

I'd rather

boost::filesystem::path::imbue(boost::locale::generator()("C.UTF-8"));

Don't recommend users to use stuff from namespace detail. :)

Sound advice in principle but that's pretty much the established practice at this point. Perhaps we should expose a non-detail way to perform the above, such as provide a function "set_utf8_as_default".

Note though that after that call all narrow strings you pass to filesystem::path must be UTF-8; you should be careful if you obtain paths from user input, files, network, etc.

Right. That's why I alluded to the alternative, using the codecvt_type overloads.
