When I use utf8_encoded, I am very strange that passing a wchar_t range to
utf8_encoded is error on windows.
You write BOOST_STATIC_ASSERT(sizeof(base_value_t)*CHAR_BIT == 32); But
wchar_t is 16 bits length on windows. I have to write some like this:

struct static_cast_to_u32 {
  typedef uint32_t result_type;
  result_type operator()(wchar_t c) const {
    return static_cast<result_type>(c);
  }
};

u16_string | transformed(static_cast_to_u32()) | utf8_encoded;
