Comment:

 This problem appears for every value type which makes problem with
 lexical_cast<std::string>().

 Here is a workaround:
 There as an overloaded version of default_value() which can be used to
 define the string representation of the default value:
 {{{
 ("test", po::value<std::wstring>()->default_value(L"value", "value"),
 "description.")
 }}}

 This string (second parameter of default_value()) is then used for the
 help output. I would recommend to use this approach.

 Please comment.
