Interesting! A fresh perspective.

Let's see what can be done within the current design. A adaptor function
could intercept what otherwise would be errors and turn them into warnings:

bool warn_nonportable_name( std::string const & name )

   if ( !fs::portable_name( name ) )
     boost::issue_warning( "Warning, path contains non-portable name: "
       + p );
   return true;

Because the adaptor always returns true, an error exception is never
thrown. This function could become the new default, or could be explicitly
coded like any name_check function.

What should issue_warning() do? How about something similar to

namespace boost


   void issue_warning( std::string const & msg ); // user defined


   void issue_warning( std::string const & msg )
     std::clog << msg << '\n';



Does that capture what you had in mind?
