Yes.

Yes, basically if you want to do it fully for standard library and boost:

std::locale::global(loc);
std::cout.imbue(loc);
std::cin.imbue(loc);
std::cerr.imbue(loc);
std::clog.imbue(loc);

std::wcout.imbue(loc);
std::wcin.imbue(loc);
std::wcerr.imbue(loc);
std::wclog.imbue(loc);

// this is for boost filesystem
boost::filesystem::path::imbue(loc);
