PVS-Studio warning V547 for Shareaza

size_t UTF16BeDecodeChar(BYTE* pBytes, size_t nNumBytes,
                         TCHAR arrChar[2], size_t& nCharSize)
{
  if (UTF16BeToLeChar(pBytes, nNumBytes) < 0)
  {
    nCharSize = MAXSIZE_T;
    return 0;
  }
  return UTF16LeDecodeChar(pBytes, nNumBytes,
                           arrChar, nCharSize);
}

In case of an error, the UTF16BeToLeChar() function returns MAXSIZE_T. This case will be handled incorrectly.

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