I think the scan loop in -getBaseDirection should be for self.length times instead of utf32data.length in the accepted answer.

utf32data.length is the size in bytes while sizeof(UTF32Char) == 4, which would result in an overrun.

In action, the current code sporadically returns false positives for identical input, depending on what it overruns onto (maybe it'll segfault on a sufficiently bad day). Everything else seems to be working perfectly with the fix.
