[vtkusers] vtkDICOMReader read chinese character problem

[Ang]

Hi David,

My character default setting is UTF-8 and the Transfer Syntax UID is
"1.2.840.10008.1.2.4.91"
.

Finally, I found the solution that gdcmReader needs the filename to be
ansi(I guess), I add below code in vtkDICOMReader at line 1460 to 1470.

***********************************************

  gdcm::ImageReader reader;

  int len = MultiByteToWideChar(CP_UTF8, 0, filename, -1, NULL, 0);
  wchar_t* wfilename = new wchar_t[len + 1];
  memset(wfilename, 0, len * 2 + 2);
  MultiByteToWideChar(CP_UTF8, 0, filename, -1, wfilename, len);
  len = WideCharToMultiByte(CP_ACP, 0, wfilename, -1, NULL, 0, NULL, NULL);
  char* szfilename = new char[len + 1];
  memset(szfilename, 0, len + 1);
  WideCharToMultiByte(CP_ACP, 0, wfilename, -1, szfilename, len, NULL,
NULL);
  std::string strTemp(szfilename);
  if (wfilename) delete[] wfilename;
  if (szfilename) delete[] szfilename;
  reader.SetFileName(strTemp.c_str());

****************************************************

Is this solution better?
