Can you construct a Mac test? The bug requires 1. Successive Unicode code points which combine to form a grapheme cluster, 2. Such a combining sequence must not occur across a boundary of 256 code points, and 3. A font which supports all the constituents of the combined grapheme cluster. I'll see if I can find such a case.
