Hello,
Why does this function not translate the Danish characters "������" correctly from wide character to character format? Well, it does but only because I put the switch statement in there:

std::string StrNarrow(const std::wstring &source)
// From http://lists.boost.org/Archives/boost/2002/10/38018.php
{
  std::string result(source.size(), wchar_t(0));
  typedef std::ctype<wchar_t> ctype_t;
  const ctype_t& ct = std::use_facet<ctype_t>(std::locale("danish"));  // no effect!
  ct.narrow(source.data(), source.data() + source.size(),'@',&(*result.begin()));
  for (size_t i=0; i<source.size(); ++i)
    switch (source[i]){
      case L'�': result[i]='�'; break;
      case L'�': result[i]='�'; break;
      case L'�': result[i]='�'; break;
      case L'�': result[i]='�'; break;
      case L'�': result[i]='�'; break;
      case L'�': result[i]='�'; break;
      default: ;
    }
  return result;
}

Without the switch statement the call of StrNarrow(L"Bl�b�rgr�d") yield Bl@b@rgr@d. Incorrect!

With the switch statement the call of StrNarrow(L"Bl�b�rgr�d") yield "Bl�b�rgr�d". Correct!

I am using Builder 6.0.
