Hi,

I'm still working to adapt Expat to AS/400. The code has a different
behaviour in following function:

utf8_toUtf8

  if (fromLim - *fromP > toLim - *toP) {
    /* Avoid copying partial characters. */
    for (fromLim = *fromP + (toLim - *toP); fromLim > *fromP; fromLim--)
      if (((unsigned char)fromLim[-1] & 0xc0) != 0x80)

--> WHY 0xc0 and =x80 ??

        break;
  }
  for (to = *toP, from = *fromP; from != fromLim; from++, to++)
    *to = *from;
  *fromP = from;
  *toP = to;

I guess it has something to do with Ascii codes. Can anyone clarify me what
does this function do?

Thanks!
Marta
