On Mac OS, Boost.Filesystem currently uses std::locale() as the default, since Apple doesn't see fit to support std::locale(""). There has been a request (ticket #3928) to change the codecvt facet to UTF-8 for the Boost.Filesystem default on Mac OS. This would at least potentially be a breaking change, so I wanted to ask other's opinions before making it. Questions: * Is UTF-8 OK with Mac OS users as the Boost.Filesystem default? * Would Linux users also prefer UTF-8 as the Boost.Filesystem default? Thanks, --Beman
