What about library provided functions, such as the following?

void
imbue_globally(_locale)
{
   std::locale::global(_locale);
   std::cout.imbue(_locale);
   std::cin.imbue(_locale);
   std::cerr.imbue(_locale);
   std::clog.imbue(_locale);
}

void
wimbue_globally(_locale)
{
   std::locale::global(_locale);
   std::wcout.imbue(_locale);
   std::wcin.imbue(_locale);
   std::wcerr.imbue(_locale);
   std::wclog.imbue(_locale);
}
