 discussion.

 The attached patch allows to gain access to the encoding-specific parsers
 by specifying the encoding type to the encoding_specific template
 parameter. This allows the following use case:

 {{{
   template< typename CharT >
   void parse(const CharT* str)
   {
     typedef typename my_traits< CharT >::encoding encoding;
     typedef spirit::encoding_specific< encoding > parsers;
     qi::parse(str, *parsers::char_);
   }
 }}}
