According to Unicode, characters 0x80-0x9F are control
characters, but characters >=0xA0 are not (and have different
classifications (at least in Unicode).
The patch doesn't say if OS X 10.5 is classifying them correctly
or not. For example, 0xA0 is a type of Space, some are symbols, some are
letters, some are a type of punctuation, etc...
Perhaps OS X is using their Unicode definition for characters defined
to be in a Unicode compatible encoding?
