PVS-Studio warning V557 for Notepad++

int encodings[] = {
  1250,
  1251,
  1252,
  ....
};

BOOL CALLBACK DefaultNewDocDlg::run_dlgProc(
  UINT Message, WPARAM wParam, LPARAM)
{
  ...
  for (int i = 0 ; i <= sizeof(encodings)/sizeof(int) ; i++)
  {
    int cmdID = em->getIndexFromEncoding(encodings[i]);
  ...
}

This is what should have been written here: i < sizeof(encodings)/sizeof(int)

This suspicious code was found in Notepad++ project by PVS-Studio static code analyzer.
Warning message is:
