The following example could not be compiled: ================================================================= #include <string> #include

int main() { std::wstring test; po::options_description desc("Allowed options"); desc.add_options() ("test", po::wvaluestd::wstring(&test)->default_value(L"value"), "description"); } ================================================================= It is due to wvalue::default_value tries to do lexical_caststd::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.
Can you please enter a bug report on svn.boost.org? Thanks, Volodya
