I don't know what you mean with 'Hex', but the codes you give there are 
the Mac-Roman encodings of these characters (the iso-8859-1 encodings are
the same as the Unicode numbers. So it seems you have a mix-up between
iso-8859-1 and Mac-Roman.

But apparently the characters are entered in mac-roman. Strange.
