Let Unicode leadingChar be encoded 0 instead of 255.
According to proposal at
http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-August/138915.html
Warning: this causes a minor bug for A macron (char value 256 & 257) because of dirty old hack in CompositionScanner
(these vales are hijacked for encoding stopConditions EndOfRun and CrossedX)
