In case it wasn't clear: what I meant is: set the locale for individual
stream objects explicitly.

Most simple example:

   cout.imbue(locale::classic());
   cout << 2.5f << endl;

(this is a bad example as it modifies the global cout, which is nearly
as bad as calling uselocale()/setlocale() or friends).

In general you would open a stream on a file and then set its locale reference
properly for that file. The C variant (printf_l(3)) is slightly
worse, as you need to pass the locale on every output call.
