I add to Scott Thatcher, that I have the same situation (64bit, jaunty). Playing with PDF/X-a1 settings just changes where the wrong characters show up, whether on embedded calc sheet, native formulas or in tables. Sometimes part of the formula has numbers and the other part has these wrong characters (some non-arabic numbers as seen in test.pdf).
