test file is general text not unicode!!
 
 
m_bUnicodeFileFormat = IsUnicodeFile(pFile);
 
==> unicode true return;
 
case 1:
 
AFX_INLINE BOOL IsUnicodeFile(CFile *pFile)
{
 pFile->SeekToBegin();
 // yayo write
 DWORD_PTR dwFileSize = (DWORD_PTR)pFile->GetLength();
 if(dwFileSize==4) // UNICODE는 파일 사이즈가 4가 나올수 없다. 일반 텍스트가 4바이트일때 유니코드로 취급된다 주의하길
  return FALSE;
 
 
case 2:
 
AFX_INLINE BOOL _IsUnicodeFile_heuristic(CFile *pFile)
{
 ...
 
 if (uDataXcount < 10)
 {
  // yayo write UNICODE 검출 힘들다.
  //return nVariation0 > nVariation1 || nSmallNumbers1;
  BOOL bUncode = nVariation0 > nVariation1 || nSmallNumbers1;
  if(bUncode&&IsTextUnicode((void*)arData, cnBufferSize, NULL))
   return TRUE;
  return FALSE;
 }
 ...
}
