[Boost-users] [tuple] set_open manipulator

Hello I am trying to remove the ( bracket from the output of a tuple. So I've called stream << boost::tuples::set_open( static_cast<char>(0) ) << boost::tuples::set_close( static_cast<char>(0) ) << tuple; however, the brackets are still printed. PS: when I used '' instead of static_cast<char>(0), gcc complained about empty character constant. Rds,
