1645	Invalid unicode support for default_value	anonymous	Vladimir Prus	"The following example could not be compiled:
=================================================================

#include <string>
#include <boost/program_options.hpp>

namespace po = boost::program_options;

int main()
{
  std::wstring test;
  po::options_description desc(""Allowed options"");
  desc.add_options()
    (""test"", po::wvalue<std::wstring>(&test)->default_value(L""value""), ""description"");
}

=================================================================

It is due to wvalue::default_value tries to do lexical_cast<std::string>(std::wstring).
Also I cannot change default_value to default_value(""value"") as soon as it accepts only something convertible to std::wstring.
In other words it is impossible to specify default_value for wstring option."	Bugs	closed	Boost 1.36.0	program_options	Boost 1.34.1	Problem	wontfix		s.ochsenknecht@…
