Re: Locale codecvt facet doesn't seem to return 'partial'

Yep.

For the record, this is what I was using.

#include <locale>

int foo1()
{
  using namespace std;

  typedef codecvt_base::result Result;
  typedef string::traits_type::state_type State;
  typedef codecvt<wstring::value_type, string::value_type, State> 
Converter;

  string from("\xC2\xA1Hasta ma\xC3\xB1\x61na!");
  string from2("\xC2\xA1Hasta ma\xC3");
  string from3("¡Hasta mañana!");

  static wchar_t to[256];
  static wchar_t to2[256];
  static wchar_t to3[256];
  const string::value_type *me = 0;
  wstring::value_type *we = 0;

  State q;
  Result status;

  //  locale loc = locale("es_US.UTF-8");
  locale loc = locale("es_CR.utf8");
  locale::global(loc);
  const Converter& cvt = use_facet<Converter>(loc);

  memset(&q, 0, sizeof(q));
  size_t s1 = from.size(); // gdb still cannot eval string.size()
  status = cvt.in(q, from.data(), from.data() + s1, me,
		  to, to + sizeof(to)/sizeof(to[0]), we);

  memset(&q, 0, sizeof(q));
  size_t s2 = from2.size();
  status = cvt.in(q, from2.data(), from2.data() + s2, me,
		  to2, to2 + sizeof(to2)/sizeof(to2[0]), we);

  memset(&q, 0, sizeof(q));
  size_t s3 = from3.size();
  status = cvt.in(q, from3.data(), from3.data() + s3, me,
		  to3, to3 + sizeof(to3)/sizeof(to3[0]), we);

  return 0;
}

int main()
{
  foo1();
}
